Yeah they are cut to put them up front too.

i'm just going to throw out an idea here- might not work... what if someone produced a spindle where the dampener mount was extended inboard 10-15mm or 20mm? would it even throw off suspension geometry? would it throw it off enough that it couldn't be corrected with adjustable suspension arms?
another thought this thread is provoking is scrub radius. at what point does it start to become detrimental in these super wide setups on our cars?

It seems pretty unnecessary - all of the interference issues are pretty solvable and the car has plastic fenders anyway - You'd probably get more bang for your buck rigging up an SLA setup rather than try to re-engineer the strut setup. BMW did exactly this with the large platform - ditched struts for a double wishbone setup
Scrub radius, I would think, would start to become an issue anytime you have to use a wheel offset down in the teens up front. If you're in the 20's somewhere, you're pretty close to the factory wheel centerline, you've just pushed the wheel and tire inboard AND outboard. Once you start adding all that additional wheel and tire outboard, and can't go inboard anymore, you're going to start to need a bigger boat. Luckily these cars have pretty stout power steering bceause with that quick rack, it'd be pretty awful otherwise

You can experiment with scrub radius stuff here:
https://www.racingaspirations.com/ap...ry-calculator/ Positive scrub radius up front will make the car very unstable under braking and will accelerate tire wear. Out back on a RWD car, it's my understanding that it actually provides some benefit with regards to caster.

I run square 18X11 EC7's with Pirelli DH 305/645-18's. I've also run the Michelin GT 30/65-18 which are a bit wider than the Pirelli but they do fit.

Nice man! I'm going to give the Michelin a try this season coming up. How do they compare to grip to the DH's and life span?

They likely have better wear longevity but albeit at a slower pace. I toss my tires after a full two day weekend since I literally try to get everything out of them in those two days. If I needed them to last several weekends then maybe it's a better option but I've run them on several occasions and I still prefer the pirelli. |

I have never heard that about the Michelin. It's supposed to be the top race tire right now, but keep in mind there are multiple tread compounds and you need to compare apples-to-apples.

Depends which Michelin slick we are talking about. I've heard the Hard compound Michelins (S8H I believe) are much slower then the Pirelli DH, but wear much better, last longer and don't overheat for long (1hr+) stints. DH is a better TT/qualifying tire, where as the hard Michelins are a better race tire. Not sure how the softer compounds compare.

Maybe my take offs are not so good, but data collected so far, Yoko are as fast as Pirelli DH. |

I have some DH scrubs mounted and some A052's mounted right now and going to the track this weekend. On Sunday if I'm where I want to be on lap-times I am happy to do a back-to-back and share some AIM data

Y'all need to be using the telemetry/data analysis thread I created a while ago. Post your Gsum traces for your fastest laps on the different tires, along with longitudinal and lateral traces. This should be a fair way to compare the tires, e.g. do they brake better, accelerate better, turn better, whatever.

That'll happen when they market a 40tw tire as 200tw
