Just returned from my trip down to NC/TN and I figured I should type a few things about these tires.
Im running 275/35 and 295/35. These tires run large and are basically like running 285/305. I am getting rubbing front and rear on the top of the fender during heavy braking and acceleration. Normal street driving there is no rubbing. (Attached some photos to show this, zoom in and youll see a soft line around the whole shoulder of the tire)
These tires overall have been very impressive, road noise is more then the stock PSS but not by all that much. They were able to handle rain and 35-40 degree ambient temps during highway cruising. They will start to float at higher speeds if there is standing water, but anything blow 65mph is stable.
I ran 32psi cold at first and this ended up being far too high pushing 40+ hot, I targeted around 35-38 psi hot.
In comparison to the PSS or similar tire these absolutely take a bit longer to come up to temp and give confidence. First mile or two of the day I would fall behind waiting for the tires but once they started to go above 100-120F they felt great to push on. That being said these tires really struggle to light off when ambient temps go below 50F, at least on the street. On track where you can safely push harder lower ambient temps might be possible.
After 2500 miles, 1800 of which was pure highway cruising the tires still looks largely new. I need to bring the car to the track this summer to decide if I should go down a size in the front but on the street there is a massive amount of lateral grip with this setup. Overall this is a very impressive tire for this car and kept the balance exactly as it should be. If you are considering these tires consider carefully the size you buy as they run a size large
As far as straight line traction they hookup very well once warm. Not as well as an r888r but not far behind. These tires have far better feel during cornering then a r888r though and to me thats worth losing a bit of straight line traction for.
Random thoughts:
- Getting used to sitting on the rear axle makes you turn in a few feet early. Really odd sensation and takes some getting used too.
- Stock brakes are not good enough, was constantly on the edge of fade the entire trip. Will need to upgrade to something better soon.
- Stock intake manifold is not up for the task and a better core is needed to keep IATs more reasonable. Will need to replace this soon as well.
- Transmission acted weird on multiple occasions flaring, soft shifting, and shift blocks even during heavy decel. Hopefully the upcoming trans tune can help with that.
- The adhesive on my HKS coil isolators failed and I now have some suspension noise since part of the isolator has come off. Ill need to get something to fix this.
- White wheels are a giant bitch and I didnt even bother trying to keep them clean.
