Race Car Set Up Forms


#1

Hey Guy’s,

After this past weekend with Scott sharing his pre and post tire pressure set ups with us (thanks Scott it really helped). I am looking towards next season to actually keep a record of tire pressures and was wondering if anyone has a source for actual forms for tire pressures, pre race checklists etc., or have you made them on your own. Any assistance will be greatly appreciated.

Hey Scott, here is a link for a good form provided by bimmerworld.

Most of the info on those sheets from pro teams are worthless for our cars. I ended up making a super simple one on excel. You cant see the grids for tire pressures here but I can email you one if you’d like:

TRACK:_______________
Event:_______________ Dry/Wet:_______________
Date:_______________ Sway Bar:_______________
Tire:_______________ Aero:_______________

I would love a copy emailed to me. Looks very simple just like me! My address is jsclough@cloughconstruction.com or jsclough1103@gmail.com. I really appreciate the help.

Hey Scott…I have a form I can email you too. I forgot to print out some before last weekend’s event. Below is link that you might find useful about tires I found on Turnfast.com:

Cheers,

I keep track of pressures only. I can’t find the excel file I use, but basically I have a sheet for each track I go to. It has the date, tire, starting cold for each corner, hot pressures for each corner, where I measured the hot pressures (pit or paddock), outside temp. Here are some other tips.

  1. Before an event fill all your tires to around 35psi cold. It is a real pain if you find yourself having to put air in a tire, it is much easier to just take it out. Obviously you need a compressor for this one. Put 40 psi in your rain tires as you won’t use them often and you often run higher starting cold pressures on your rains. Since you have the air out check the air in your spare trailer tire, you have a spare right? :wink:

  2. Always, always use the same pressure gauge, buy a good quality one once and only use it. I’ve seen differences of 6 psi between gauges and it has caught me out before. Take this into account when getting tire pressure recommendations from other people sometimes their 30psi might not be the same as your 30 psi. Compare gauges if possible if you really want to use their setup.

  3. When I get to a track I have data on I start the first session slightly higher than I think the optimal cold pressure is going to be. If I have no data I set them all the same higher than what I think the highest cold is going to be. Set them early in the morning before the sun comes out. Run the first session and set them hot in the pit if possible, failing that set them in the paddock as soon as you get out of the car but keep in mind they will lose a couple of psi compared to setting them in the pit. Also keep in mind how you drove the session, were you really on the limit 10/10ths or were you kinda warming up 8 or 9/10 ths, how quick was your cool down lap? it will make a difference on where the hot pressures are. Be honest with yourself, you will often drive harder in Qualifying and the Race. After the first session try not to reset the cold pressures just leave them alone and adjust hot. If the sun gets on them if will screw up your cold pressure setting. The following morning get the cold pressures again to see where you ended up. I usually don’t mess with them much after this point, as I’m lazy.

  4. Generally I aim for all the tires to be the same hot all the way around. But if you have a handling problem you might adjust pressures to try and compensate. This is not something I usually do but is just something you might experiment with.

  5. Figure stuff out for yourself. There is a ton of misinformation on the internet and a lot of different variables that effect the tire pressure. Just look at all the different opinions on the R888 already. Because of this don’t blindly follow someone elses pressure recommendations, even if they are fast on the track. You might use someone elses setup as a starting point but ultimately you need to figure it out for yourself what works. Getting the right pressure will help, especially if you are overheating the tires or they seem to be going off during the session but it isn’t going to be a big time gainer on a single lap. It will help on the cumalitive race total and might make the difference of slowing gaping someone or catching someone over the race distance. Just don’t think you are going to suddenly drop seconds off your lap times because you have the right setup, you still need to drive the car :). I guess what I’m saying is don’t kill yourself working on setup, working on the driver is much more important, especially since we can’t really adjust much. I like to run what I brung not work on the car trying to figure how to make it faster. Its one of the many reasons I like Spec E30.

For sure, very good advice…from the guy who passed me on the last lap of the Championship!

:angry:
