While searching to see if anyone ran a 305/35 front tire, I found a member who ran rears on the front and was very happy. So they will clear with factory 295. But I think I'm going to get silly and just run 305/35 to see if they work because I like a meaty tire. Going to be a bit of a downsize from the Viper's 315 front tires (335 rear). I don't want to run too wide of a rear on the 575 because I would rather have some wheelspin than shock to the driveline/clutch. But I'm going to be running an 11" rear wheel, so that should give me a decent amount of options. The suspension is far too stiff for most people in its standard spec (would be great for a track car) and the rear upper perches are very difficult to access for adjusting the dampeners. So I'm working with Fortune to create some variations of the coilover with some options as standard in the kit to make it easy for anyone to install on their car. If you want any details, feel free to message me. I mocked up my Viper's 13" wide wheel with 335/30 tire and there was a TON of clearance. I was amazed the 575 had that much room. Yeah, that's why I'm leaning towards 305 R888r over a wider tire. So it can have grip, but allow for some slip. The tires on it are useless (340 treadwear), it's like an AMG65 powered car with the traction control off. Rolling into the throttle over 3000rpm in first results in wheelspin. Simply switching over to a stickly tire in OE size would greatly help.
