Very fun! amazing engine sound and hilarious to drive!

Using a honda NC700 powertrain, a hybrid fiberglass and steel structure, and common buggy and 4 wheeler parts I present the working protoype of the Rodensa 670...

It has 165r10 tires. a crude swing arm suspension in the rear. Is chain driven. and uses a short stroke mcpherson strut in the front. Running on Minator 10x6 wheels, this sprightly little devil needs to be driven flat out almost all the time. It also has very poor aerodynamics, and can only break 100mph in a draft. The COG height is pretty high due to the engine design and driver placement! So be gentle with the steering and heavy on the throttle.... It doesn't tip on it's side, unless you really make it mad... Like poking a small inexpensive bear with a stick... Not a great idea, but not the worst either.


I am going to try to make the model look as fun as it drives. If anyone wants to test drive it before it's complete, pm me for the files.

1;01.45 around SO1 is my best time.

EDIT:

Why Rodensa? Because rodent isn’t catchy or fancy sounding.

.5 to 7 Bar is the actual range that I use in real life. I have heard of up to about 8 bar before but that’s definitely excessive. Tires come off of beads at 8 bar.

I drove the car, it is very nice!! It feels dangerous and stable simultaneously. I think that’s accurate! Ha

Hooray it has been approved as a WIP. I would love to hear feedback about it and peoples thoughts. It really won't seem normal, but I assure you it is meant to be that way!

[edit]
Ok so I got some very negative feedback on it! I went back through it and changed some characteristics and I think it’s really improved now. While you could throw in a very flashy reverse entry, It was not holding a wide line on throttle, making it hard to connect drifts. It also had a bad under steer during critical moments. I changed the COG to be lower and more forward, changed the KPI, SAI, extended the LCA a little bit. Changed the rear camber curve to be more aggressive, helps prevent too much rotation, which was another problem! I also adjusted the engine to be a little less peaky. Now you have to clutch kick to get it to spool properly, but it is easier to drive around drifts now as you blip the throttle rapidly.

Here's a tip on how to drift this style of car.

Speed up in 3rd gear, gently turn to the left as you're flooring it. The car will drift slightly to the left.... Now, crank the wheel 90* to the right and pop off the throttle. Now counter steer very fast!!!....hold the clutch in, hold the wheel max to the left... Keep the gas floored and wait. you'll be sliding very hard now, wait, wait... Then, drop the clutch and return the wheel to straight!

You'll shoot off like a rocket!

Quote from timdecnodder :

If anything, the car is underpowered in comparison to RL RX Supercars(T16 = 440BHP / RL Supercar = 600-700 BHP) the car itself is a standard car with rollcage added, engine is mounted centrally in compartment behind the driver( Groub B like).

Oh wow, People have some crazy fast cars in real life! I'll keep driving it for fun, it is a good one!

I gave the suspension a fix. Adjusted the tires, though they're still relatively small, it is a realistic "Shakotan" setup and in real life would probably be called "Meaty" in the JDM crowd. I think its pretty nice to drive, I do think the boost should hit a little sooner and a lot harder, but in reality it does feel like a mildy tuned UZ to me! It feels a touch soggy on the default setup, but I enjoy it! No doubt it could be tuned with more racey sets! But overall, a very nice mod! I love the interior too, it really adds to it. We will see if Mr. High Speed Garage will approve of the suspension soon!

Les Collins LZ20B could be a good reference

I drove this car around a bit. I really enjoyed the default differential settings. It is an interesting car, it feels like a fiberglass shell over a roll cage from the cockpit. Maybe the car is too fast as well, but definitely has potential.

I’m laughing at the fact that we have lawn mowers and probably will have tractor pulling soon.

I've redone the XRT to have a quite realistic Japanese style essence, in my opinion. Most of the work has been done to the suspension, engine and weight setup. I did tweak the body, the wheels and tires, steering wheel, driver animation, etc as well...

I've redone the rear suspension to mimic a Silvia as best I could with double a arm, and the front Mcpherson design has been tweaked heavily.

Anyone who tests this car will realize that this isn't just an XRT with extra power, it drives unlike anything I've tried in LFS thus far, in a good way.

It might feel a little weird if you haven't tried a car like this in real life but it's definitely worth figuring it out!

I do need help figuring out how to let other people try it!!

That’s perfect!

It would be just great!
Sorry, I can't send you PM, because you chosed not to make use of the conversation system.
How can I contact you?

i have attempted to send a message!

I have talked with a rally suspension engineer in the past and he explained to me that most rally cars will have about 200mm of damper travel on a McPherson strut. It’s not uncommon to see less though, 170-180 is very common also. The WRC cars have extremely expensive setups to offset the struts and gain 220-240mm. But that is definitely not affordable. You could probably see about 220mm of total rear wheel travel and about 180-200 front wheel travel. Many many fwd rally cars use 35-50mm offset wheels. 15x6.5-7” is very common or 13x5. 175/70-15 or 165/80-13. The included angle of the strut is probably between 9-12*. So if you set the camber to 0.5* negative, the included angle to 9-12* just enough that the wheel offset doesn’t hit the strut and the scrub radius is slightly negative (inside of the Strut top to ball joint line). You will end up with a very realistic setup. The caster should probably fall between 3.5-5*. A realistic front lower control arm length, in my experience would be between about 270mm to 320mm. The rear lower control arm length would probably be no more than 400mm, that’s probably a bit longer than realistic for many cars but Subaru rear lower lateral links are about 400mm. They’re pretty much the longest of anyone.

As far as 18”. The R5’s use a 20-65-18. Approximately a 225-40-18. The smaller XFG with a 205/40/17 would probably fit alright. Keep up the hard work! Good luck!

Also it is hard without helper springs, but gravel setups don’t tend to use a helper spring. They over damp the suspension to absorb the bumps, and tend to run lighter springs with preload. 5-6kg for a dirt setup is probably the max. With lots more compression damping than a tarmac setup.

Awesome car!

That’s a great looking model Vladimir! I’m so excited for your work

My 3 year old daughter who is learning to drive on LFS with a sim rig will absolutely love this burger. Hopefully there will be a simple 2 cylinder 20-30HP version so she can drive it easily at WOT! (3 year olds have a hard time modulating wheel spin!) she loves to drive around Aston and Blackwood X maps looking for “secrets”

Awesome mod!

PM me, I have worked on lots of drift cars in real life, including the JZX81. I’m sure I can help you sort out the suspension for it

I still play the game often, usually offline with tweaker to test things. But in general it's a good tool that I've been able to help figure out real life car issues with pretty well for that. I hope there is more someday! Eventually!

This has been happening for over a year now with all of the new updates the problem comes back.

I reinstall it fresh and it works fine. Go to download the new updates automatically and during the download my screen goes black. Restart LFS and then it's black forever. Sometimes the error says something about path update, sometimes it says could not set up FF steer device. I am retrieving the messages by pressing T, then up arrow and then ctrl + C.

I think it also might be doing it after I unlock S2. I really am not sure. Sometimes the game works fine for for weeks at 60fps. other itmes it is permanently black! I have tried turning off anti-aliasing through CFG. I have tried turning off V-sync. I have tried deleting CFg and letting it restart itself. Nothing works.

Please help!

EDIT:

After screwing with it over and over I found something that sets it off. If I delete card_cfg and cfg then restart LFS it (obivously) makes me reset my driver settings etc but it will work until the screen is swapped from windowed to fullscreen. OR even if I just accidentally hit maximize/minimize while its windowed. Then I have to delete CFG and card_cfg again just to get the screen viewable again

go to the street sharks server theres a team speak and do tons of tracks

This update is nothing short of amazing for me!
Westhill looks amazing! and my game runs at DOUBLE its old framerate. I don't know what changed but on my not that great laptop i am seeing over 110fps where i used to see 30 or even 20 in some places.
thank you!

I hoped for more cars and tracks too, but LFS is still a very good
game. It may not be as entertaining to us, because we are used to it.
but it's still a great game! It has not gotten worse with time, it's
just very stagnant.

Play other games, enjoy them! If you're like me at all, you really
hope that LFS becomes even more advanced, for me that is because I
think it has a lot more potential. Until then, what can we do?

The Body kits and frills wasn't aimed at anyone in particular. I'm not trying to attack anyone

It helped my real life driving and that's invaluable to me! I hate that I can't get the graphics decent, but I've been itching to buy a g27 and get back out there in the XRR and learn how to drive a race car again!
