Do not run the R10's at the Glen, Run the 12/10's at the Glen. I run R10's on the street (for the past 10 years) Just sand the rotors with 80 grit paper to remove foreign pad material and the pre-bed pads will transfer to a clean rotor.

What are you running on the rear?

Side to side(axial) or radial movement?

We offer a KIT for that.

Per Torsen, it should make it work better in a road course environment because Torsens work off of friction. Because you are never loading the tires "equally" through a turn it will help feed power to both wheels more evenly before it starts splitting torque. The issue with Torsen's is if a...

For track use we do not run it, for street use you want to. For the same reasons it is used in the Clutch type differentials. Most modern lubes have a version that already has Limited Slip additive in it. Running the additive in the Torsen calms it down. The Torsen can unlock in a harsh manner...

For the deal on them it wouldn't matter but the ported heads have different flow characteristics so companies like GSC offer different valve events to suit the flow curves. OZ tuning has done a lot of tuning development for several cam companies, if you end up putting the comps in.

Do you have the Long block with ported heads or the short block with stock ports?

All of that will be gone 1 mile from the dealership.

We were referring to our studs, not the OEM ones.

Wire Brush and a WD40 Soaked rag. Helps keep things preserved. The rusty hubs cause stud failure because of the rust building up under the rotorhat and hub. The wheel does not clamped properly. Once the wheel runs loose, the studs will be subject to bidirectional forces. Keep them torqued...

If you think that's bad, don't remove the rotors to look underneath. #1 cause of wheel stud failures. Take it all apart and wire wheel everything, wipe it down with WD-40. Wheel cleaners that contain any level of acid is like driving in the ocean.

Is your car 100% stock?

Not sure why anyone would spend forged wheel money on anything but an 11" wheel, but ....

Apex Forged VS-5RS. We have 315's on them. Looks like they have a narrow tire up front with the front offset. We run a square set up.
