285 squared is the route i believe now for road course/autox is the best and safest for these wheels 19x10 ccw on route 15mm and 21 mm offsets my thoughts now are on which tire dia for fender clearance as my ridetech coil overs are still on a 10" spring which requires a 6.1 back space(15mm offset)

325s





305s on these two...

I have 19X10 CCW's with 285 bridgestone RE-71's. Car is lowered over an inch - no issues with fender clearance. These are my street setup.

Plenty of Issues with clearing speed bumps however... I avoid them like the plague.

My wheels arrived so light!,offsets are different for the better CCW 10" 15 and 33 offsets.
i need to polish the rears to match the front sets highly polished finsih but they are new
and with a 10mm spacer up front I can run the 305 30 19 set up and will probably after my 285 35 19 re-71s are worn, my wheel calculator actually specd 9.5" wheel minimum for that tire not that it is correct over the manufacturer

My tire shop is having a heck of a time mounting 305/30/19 RE71R's onto my front 19x10 Forgestar CF5's, they just can't get the bead to seal but I know for a fact they fit as these are the exact wheels that came off of an autocrossed SS 1LE running the same tires.

Bretts are you in Calgary or Edmonton? Any plans on autocrossing with the SASC this year?

I spoke with their engineer as I too was surprised by this decision as I thought in a street class car you'd want to do anything you can to increase spring rate and running high N2 pressure is one way of doing that, but in their testing on the Koni twin tube's that the best set up and it does result in a slight reduction in ride height.

94 boosted I am on the Sask Alberta border 3 hrs from the badlands site underway 2.5 hrs to Red Deer where i get a few runs in, definitely interested in doing some drop ins with you guys a buddy runs with you guys I believe. My tire guy has no problems with the 305 30 19 in terms of doing it for me, might have to as mid June currently for the 285 set up , will be a big step as would probably get new hubs for the extended studs that i would need to clear front suspension via spacers

Not every machine works well with low profile stiff sidewall tires. Shop around.

My tire guy had quite a bit of trouble with my RE71s on OEM Z/28 wheels. They specialize in high end Porsches, lambos, etc do they are no strangers to wide, low profile rubber.

The Camaro came from behind to beat out that other car by 1/10th of a second.

You need to find another tire shop.

I had my Koni's custom valved by TrueChoice and they actually run a lower N2 pressure than you'd think, arguably just enough to prevent cavitation of the oil. I spoke with their engineer as I too was surprised by this decision as I thought in a street class car you'd want to do anything you can to increase spring rate and running high N2 pressure is one way of doing that, but in their testing on the Koni twin tube's that the best set up and it does result in a slight reduction in ride height.
It would be unusual for a car set of twin tubes to be high pressure N2. You'll find that more often in more performance oriented monotubes.
