Xian, since you are in florida, are you planning on going to the Sebring autox on Saturday and/or the 3palms autox on Sunday this weekend? If the weather looks good, I plan to do both.

Nah, I'm in NE Florida... Sebring is a solid ~3.5-4 hours drive. About the furthest south that I go is Gainesville or occasionally Orlando.

I'm going to try the Rival S in 315/30/18 on 10.5 rims on all 4 corners. Any idea on pressure?

thanks,

Steve

Yep. I haven't tried running them square on the car but I'd start around 36/32 and be ready to bleed down the front OR let it grow a little depending on rollover.

How light is the car? 315s on a 10.5 are a little pinched so I might run a tough high, some thing like 32/30 depending on how your car is balanced.

I won't claim to have anything more than seat of the pants "feel" and watching should roll to base it off of, but I've been running the Rival-S higher than I ran the 71R/Z2SS. We ended up at 35/32 at the TnT on 275/315's and I'd also expect the 315's to roll over more on the front of the car than the 275's. I guess something to remember is that rollover and wear aren't necessarily relative to "fast".

I've been running Bridgestone 275 square on 18x9.5 and 18x10.5 rims. That was my A Street setup. Looks like the 315 Rival S in the rear might be the hot setup for A Street. Pick whatever 275 front tire you like. Bridgestone or BFG's. Since I hardly ever run A Street, I'm going to put on 315's on 18x10.5 rims square. This should be the fastest setup for all my none SCCA events. So far, I've wasted $2500 trying this stupid street tire rules/events.

Any one running a 275 square RE-71R setup on a base c6 z51? I'm currently running 255/40-18 fronts and 275/35-19 rears. I came across a great deal on some used 275/35-18s so I'm thinking of trying them out on the fronts as the c5z guys have been doing. The main reason I'm holding back is the fronts are only 8.5" wheels as opposed to the c5z's 9.5"

Here is a 275 on a 8.5 c7 wheel, it looks fine, just mounted it now

That looks pretty good. Was it a pain to get it mounted? I've heard pinching these tires can be hard to install

Mounting was same as the 245 that came off, I'm not sure what you can see but from this end its not pinched, well not like a 315 on a 9.5, or the 335 on a 10.5 I ran once, also this picture is for bobofhousewheels that told me that this base 18 inch wheel not fit my z51, they fit BOB thanks for the wheels, SS here I come

I'm going to try running 275 bridgestones on the front with 315 bfg on rear on 10.5 wheels. After watching all these people go fast up in norcal, I've jumped on the bandwagon. Re71 for turn in and response, bfg for putting power down.

DAVID -

If you are going to SS class with 275 RE-71R's up front, what rear tire size and brand are you planning to run on the 19x10 stock/base wheel ??

Last week the re71r was released in the c7 factory size 285/35/19 , I wish it was a 305/35/19 but this will work well until then ( I have a tire I'm not proud of on rear now till it burns off) but the re71r is next! FYI the re71r even comes in 245/40/18 so if anyone wants to run 1sm in NCCC they are also setup.
