Great work

You did it ! It's fantastic. Thank you so much !
But where is this car? You no longer have a published mod?

refresh ur list u will find the car there still few things to do on the car but physics are done.

Your e21 GR.5 is awesome. Physics, engine sound and handling are good. The car is very easy to control. An ideal car for LFS.The weight of the car may be a little high.

It would be fantastic to have a full Group 5 grid with an Escort Zakspeed and a 935 Gr. 5 turbo (wish I could find the time to do that)

Are you going to give your GR.5 a more racing look? For the cockpit, for example? Or add things to your body kits like the aluminium fins? (in the link below)

I think your already awesome car would gain in charisma with these details and some racing skins (there, I might find some time to do some).

Thank you so much Houssem for this great car. I have fun with it like a kid.

i'm glad you enjoyed it , for car weight i did research and it seems its around 780 - 840 kg most of info are different a bit, i tested in lfs and i found that higher is better for stability specially in cornors when u hit curb for example sometimes car flip but for what it is now its more stable.
and ye sure im not gona leave it like this i have to do a skin for it at some point, also i may add few details like u say it shold not be that hard, i think its harder to do cockpit details but will see.

There are indeed many versions of this car, with different weights and powers. For example this turbo version of McLaren.

You have made your choices and they are consistent. The car is indeed very stable and easy to drive. As you know, in a driving simulation, your feeling depends on how you play? When you try to get closer to the real conditions (steering wheel, cockpit, screen and real size fov) too much stability can seem a bit artificial. In LFS (this is just my opinion) the super-road tires slip too much and the slick tires seem to me to stick too much to the track. The new tire physics will no doubt correct this and/or will make driving more subtle.

To give you another example, I drove a stock e21 in the late 80s/early 90s. From what I remember, I have the impression that if I'm still here to tell you about it, it's because it was more stuck to the road than yours . With your Gr.5, it's the opposite. I feel like it's very stable. But, I have never driven this car in real life.

What I'm sure of is that your mods are great with LFS. Great job.

Ye man thanks, I totally agree with you cuz when I was doing testing the R2 slicks seems to have a lot more grip then what the car should have and R3 feels little bit better, the problem is they never go up in temp even if u drive it hard that's why I pick the R2 in default setup hopping new lfs update will fix this.

And also turbo version of it with 600 hp doesn't seems bad idea at all I may consider doing it also

With 600 hp, the car should be harder to control and the R3s will heat up more. The idea is pretty good

Having several engines on the same model is also a good way to make your work profitable and to satisfy the community more broadly. I think a lot of us like racing cars. Modding has already produced a lot of stock cars.

I can't wait to see more of your work .

Regarding the choice of tires, I tested your E21 Gr.5 with R2s. You're right. R2s are better for the default configuration. The grip on the track is a little strong but the weight influence is much better. Feelings are better too. The ride is more subtle and realistic.
Indeed the R3s do not heat up (30 laps on Aston Cadet Rev against FXO & XR GTR and still in the blue) and slide too much in tight turns. This has the effect of reducing the effect of mass transfers. I don't know if what I'm saying is clear (bad English) but the wheels "lift" less when pitching and you feel the weight of the car less than with the R2s.

what i notice is lfs road cars feels the best and most realistic specialy the low and mid HP (100hp - 300hp). but race cars like gtr class or gt3 (most of cars that use slicks)they dont really feel that mutch realistic, and slicks in lfs has so mutch grip that if u pick road car and add slicks to it u will flip almost every cornor and u will have to adjust the frame of the car to lower the cog (center of gravety) so it can hold it self but that will also effect weight transfar and effect the natural feeling of the car sadly, hopefully tire physics will solve this.

I have also tested slick tires on road cars and ended up on the roof as well .

I generally agree with you, especially on the excessive grip of the slick tyres. I stopped riding the LFS GTRs because the slicks grip too hard. But I find that road tires have the opposite problem. It slips too much. That's what I was telling you about your e21. The real 323i slides less, fortunately (on a dry track).

After a lot of testing, I tried something overall satisfactory (more realistic for me) with extra wide, low profile super road tires. It doesn't stick too mutch, it heats up normally and it doesn't slip at too low a speed. It's fine for me while waiting for the tire update (I'm playing offline against the AI).

If you haven't tried it yet, I recommend this excellent Racon mod. These tires are the best super-road tires I've tried (that's my personal feeling).

ok sure man will do

That car gona fly! Like Group 5 cars

I disagree with u in that. Most LFS GTR cars have really fat tyres and that's the reason why they have so much grip. Try GT3 or other cars with smaller tires or even some road cars with tyres like ~225/35. Not all road/street cars flips with slick tyres. It depends of roll center, camber gain and suspension hardness and other things.

IRL tyres of similar type can be very different if u compare products from different manufactures. LFS slicks are more like tweaked road LFS tyres. They are kinda wobly because of soft sidewall. Tyres used in rally or GT3 have very stiff sidewall and they relay more on compund grip. Of course it doesn't means that all slick tyres have a lot stiffer sidewall than in road tyres because like I said, it depends of manufacturer and purpose of use.

Would be nice if devs someday allow us to tweak tyres compound, sidewall stiffness, grip on various surfaces and some other things for our mod vehicles and maybe find a way to not allow making overpowered ones.

I disagreed with myself on this issue not long ago. That's why I tried to put slicks on other cars without much success

Here I was not talking about all the cars from LFS. But precisely big GTRs that have very wide tires that grip too much. It's a personal feeling. There is nothing theoretical in that. The feel depends a lot on how you play and what equipment you use. LFS is a game. A very good game, but just a game. If you have a mod to recommend that has slick tires that you think are realistic, I'd love to give it a try.

To clarify my point on slicks, I have enjoyed riding FZRs for a long time. Still, this car has very wide slick tires that grip a lot. But, over time, I started to get tired of never being scared behind the wheel: that unpleasant feeling of being able to do almost anything without risking losing control. I have since reverted to less powerful cars with super road tires and find their handling more subtle. But I really appreciate the Gr.5 of Houssem, even on slicks! The success of a car depends on a set of complex parameters that go beyond the simple question of tyres.

I also think it would be nice if modders could do more with the tires. We would thus have a greater variety of behaviour of the cars. The next tire update should also bring us some enjoyable surprises. If the current tire physics were fully satisfactory, there would be no need to go back to it.

hmm what u say is intresting, i think we have side wall tweak but probebly just visual, i dont know if there is effect, low profile tyre style 1 or 2, u find it in wheel object.

hi again , i notice that the tires actually change shape of side wall u can see the small deference in pic.

also Avraham Vandezwin u will find a car i added u in called (BAVARIA A30 V3) its fully stock car that i made with factory tire size, default set use normal tires, it will be intresting to see ur point of view about how it feels.

Hi Houssem,
I'll try to test that tonight.

I was only able to do a few laps yesterday. I will tell you a little later in detail all the good things I think of your 325is (perhaps on a dedicated topic?). Once again, you have an excellent basis for making a very nice track car .

About the road tires, my opinion remains the same. Even if your 325is chassis offers very good sensations (moreover, it supports slick tires quite well, I couldn't resist ).

First, I want to clarify that I am not a test pilot. I have driven a few BMWs in the past, including the 323i e21 & e30, on open roads (never on track) but at a time when you could still have fun without risking prison (provided you didn't kill anyone ). Many people here are more qualified than me to give their opinion on LFS road tires. I don't know how these tires are handled in LFS code. I give you my feeling according to my memory. It's been a lot of years since I stuck my ass in a real propulsion from that era. I can totally understand that people don't agree with me about LFS road tires.

With road tires, the sensations are quite good in curves with your car. In tighter turns, it doesn't look like much. None of the propulsion I've driven in my real life have been hunting like this from the front axle at very low speeds, or with dead shock absorbers and very worn tires. And normally, when you lose grip, you find it very quickly (fortunately ). With the LFS road tyres, the slip is controllable, but without any real grip recovery. We go almost on/off from the grip to the glide and at speeds that always seem much too low to me. What I'm saying here is obviously much less sensitive with very underpowered cars.

With super road tires, your car finds a credible behaviour, and we start to have fun. With slicks, we think that a real racing version would be welcome .

ye i want u to test deferent car just to get idea of how things work in lfs with deferent cars and specs and personaly i think the 325is feels just right in grip levels but it will be even better cuz im sure that the update will fix alot of things im very exited about it.

Can you tell me what you think of the grip of your 325is on Aston cadet rev, please? I'm curious to know what you think about it. It's a very good test track for grip (I think).

Edit: I ask because I agree with you that the grip on your 325is is generally good even with road tyres, except in tight corners like the Aston cadet rev. Even at low speed. It's this kind of aberration that I would like to see corrected with the new tire physics.

i did few laps for me car feels good i do understand what u mean about tires feel when exist cornors like 180 degrees i notice car oversteer little at first cornor exit after the bump but it correct it self (very safe) and in last cornor and cornor before last it slide little so i use 3rd gear to exist safe most laps where 1.04, tire temp was consistent at around 50 temp, i enjoyed it

in general its kinda hard to judge the feeling of tires with low hp cars (they do perform good but not quite realistic) but it also depend on car specs and how heavy it is.

btw i will send message derectly to u so we can talk from there its better then talking here its not the right place.

Yes you are right. Sorry.
I will do further tests with this superb car .

Great car

amazing mod
