How To Make a Car As Fast As Possible?

[Crumpet]

Last night my Supra was beaten by an R34 GT-R at SSR7. He didn't get too far ahead, though still managed to go slightly quicker.

I have this car tuned already, it gives out 725 BHP and and all I have done is lowered it. I'm wondering if there is anything I can do to the car to make it able to reach a higher speed than the R34. My knowledge for tuning has died out.

This is about straight line speed, anything that can sacrifice cornering or braking to make the car quicker, please mention that too.

So, what do you think I can do?

The more downforce you put on your car the lower your top speed will be, and you'll want to play with your gears to get the best balance with acceleration and top speed. You'll usually want to hit your rev counter in your last gear, at the end of the tracks longest straight.

There are a couple of things you can for top speed tuning:

Remove any wings of aero you have on your car. Supra is standard (unfortunately) so just remove the wing if you have one installed.

Make sure camber and toe both have zero values, this is done to make the tires contact the road surface at an optimal tire footprint.

Next you want to reduce lift on your frontal area of the car. Do this by lowering the front of the car to the lowest point. Slightly raise the ride height in the rear, this helps acceleration (weight transfer, also creates more grip when acceling) and travel at high speed when the rear will be pushed down by downforce/air/etc. Travelling @ 3 digit speed will push the nose into the ground hard so make sure that springs and dampeners have high values in the front and slight to moderate difference towards the rear.

Gear ratios for the higher gear should be focused on the power band ie. @what rpm does the car make peak BHP.

Hope this helps.

Great info here. My Supra is only tuned to about 400 hp but I have found that it likes very tall gears because of all the torque. You will want to set the top speed higher than the car will go to take advantage of the broad, low power band. Only testing will show whats optimal in your situation. Also, play with the LSD settings & soften the rear suspension to get a good launch with minimal wheelspin. Hope this helps.

This is very useful, thank you sir.

I generally agree with this but interestingly, I have seen some NASCAR setups with high ride heights that are faster than setups with low heights.

Game does not equal reality. Generally there are loop holes in all games, gt5 included, however i prefer to use real life logic to setup cars cause otherwise i think id go crazy.

I don't think the game aerodynamics are that sophisticated. What you describe would require simulating airflow over a 3D model. The computational power alone would be ridiculous. Downforce is most likely simulated by a simple formula based solely on downforce settings and velocity, nothing more.

Yes sometimes happen to find setups with insane values that works in the game, but until we don't know every single tuning exploit is much better to keep real life logic.

I'm already going crazy because I made two tunes on the same car, one with -10 ride height and another with -25 ride height. The -25 was almost 2 seconds quicker on Tsukuba. So the NASCAR thing has me scratching my head...but I threw it in this thread to see if others have found a correlation between height and top end speed.

i think my skylines lowered by 20 on back and front and reduce the down force as much as possible its also running at about 790bhp although its slowly increasing the suspension is also very stiff but i found it hardly breaks traction my tune was of

Yeah, that's about as specific as someone asking which city you live in and you answer Europe. Include something informative next time.

Can't remove the standard wing, and having an aero wing doesn't affect top speed with speeds up to 350km/h which the Supra barely reaches. 👍

Make sure camber and toe both have zero values, this is done to make the tires contact the road surface at an optimal tire footprint.

I would totally agree with you with that if we were racing in the real world, but unfortunately with GT, this isn't the case. If the drag secrets in GT5 are similar to GT4, then you will find that using toe angle actually helps in straight line races.

Next you want to reduce lift on your frontal area of the car. Do this by lowering the front of the car to the lowest point. Slightly raise the ride height in the rear, this helps acceleration (weight transfer, also creates more grip when acceling) and travel at high speed when the rear will be pushed down by downforce/air/etc. Travelling @ 3 digit speed will push the nose into the ground hard so make sure that springs and dampeners have high values in the front and slight to moderate difference towards the rear.

Once again, totally agree when it comes to real world tuning. In GT however, you want the complete opposite when it comes to ride height. For straight line speed in a RWD or AWD car, the best is having a high front and low rear, and high rear and low front for FWD's. However, you're right on the money when it comes to the springs & shocks. 👍

Gear ratios for the higher gear should be focused on the power band ie. @what rpm does the car make peak BHP.

Hope this helps.

Wonderful advice. 👍 You give me hope that the other new tuners can learn from this, mainly from you (and others like you) showing the car knowledge you obviously possess. As you'll see, GT is a bit ass-backwards when it comes to it's settings.
