I will be fitting some coilovers shortly and would really appreciate some help getting the ride height set. Car is a partially stripped 2010 250 cup, will be fitting BC coilovers. I would like to know where I should be taking the ride height readings from (under the chassis at a given point or wheel centre to arch ? ) and also what height I should look to achieve. Car will be used for mainly track duties but I will be driving to and from the ring a few times a year and also some fast road fun !
With the amount of people that track these cars you would of thought someone would of chirped in by now. Maybe they can measure from the floor to arch for you
That would be great. Did you have this setup somewhere ? I would just like to get it set something like before is take it for corner weighting and geo.
I had the whole thing fitted and set up by CGR, great service transformed the car on track but still enjoyable on the road.
That would be amazing thanks I take it at it's current height you did not require driveshaft spacers ?
We measured average of 383mm front and 373 rear, wheel centre to arch standard We will start with say 355 front and 360 rear and see how it goes. As for negative camber we will go for 2.5 deg front and between 1.5 and 2 deg at the rear If we need to go lower I have a shaft spacer ready although I would prefer not to use it if possible. Does the standard shaft nut fully engage with the spacer on or is there a different nut type available ?
I measured mine this morning, 630mm from the floor to the wheel arch, that's front and rear. Thats with 19 inch wheels and i still have my track day wheels and tools in the boot.
I always thought the back had to be slightly higher than the front. What alignment are people running. - 2 camber and -5 toe
They definitely drive better with 10-15mm of rake in them, Makes the car a lot more balanced and more oversteer/neutral balance
That's what I thought. Cars sat at 650mm floor to arch at the minute. Do you think it would benefit being lower
Erm, I can't remember what mine was from floor to arch but front was 325mm from hub to arch IIRC They do drive better when not slammed though
Jamie - where are you measuring from, wheel centre to arch ? Ah - looks like we posted at the same time !
Yeah that, means tyre size isn't affecting it so much I ran mine at countless heights and setups, Got a folder full of different geo printouts easy 25+ in there over the years lol
Depends how you like to drive and the rest of your setup tbh If it's mostly track then - 3+ front camber, rear I ran - 2, bit of toe out on the front for turn in and either parallel on the rear or some toe out to get the back end moving. Although rear toe out makes it pretty lively so not for all I'd also go stiffer rear spring rates depending on what setup your running, I ran more rebound and comp damping on the back and it made it ultra sharp and pointy
