Hello all,

Just picked up a 1998 Formula that I will be prepping for ESP class in SCCA Autocross. It's Blurple, but I don't care too much about my cars look (IMG:http://www.frrax.com/rrforum/style_emoticons/default/smile.gif)

I have some other things to take care of first, but wheels (17x9 or 10+) and suspension should come soon. I plan on Koni yellows and GC coilovers.

that is awesome. good to know. why did you choose the eaton over the other options?
did you have an auburn in there stock? i have 98 formula too (slicktop as you called it) so I think we'd both have auburns.
You still on stock LCA's and TA?

Can you run 315's on all 4 corners under stock fenders using 10.5 c5z06 rear wheels?

I'm jelly of your lowering springs. I'm on stock 1LE springs and its like a 4x4.

A local C5 guy here is running 315s front (17x9.5) and 335s rear (18x10.5) on his car... but they have double wishbone rear and I'm told they have a better camber curve?I'll eventually move to an 11, but I'm not going to pay 315 $$$ to run it super stretched on a 9.5.

*edit* That's not what you were asking (sorry). Yeah, All of the ESP guys I know of run 315 A6s, but they are on 17" rims. I see no problem with running them on a 10.5, but you might need spacers. My 18x9.5 Wagon Wheels rub on the back, I have ARP studs and run a 1/2" spacer. They are 56mm offset

My previous region's ESP group went through most of the diffs, and the Eaton clutch diff is the one that holds up to 315 A6s on all 4 corners. The helicals and Auburn Racer's diff didn't last long. My car came with the "Zexel-Torsen" diff. It didn't work after 120,000 miles.

The Strano Springs/Konis/bars and rear diff made this car go from a floaty boat to a heavy-set athletic girl (IMG:http://www.frrax.com/rrforum/style_emoticons/default/smile.gif) All the new people that walk up to me at Autocrosses seem amazed that the thing can turn corners, and I'm a midpack driver. I would really suggest getting the suspension kit if you can, it's worth it.

Has anyone actually rebuilt the Eaton CF clutch pack Posis with the stronger springs available (800# I believe?) to run autocross/open tracking/etc.??

Or would that make them even worse than a locker as far as being too 'spool-like' for corner exits/slow apexes/etc.????

Racer X Has a rebuild kit for his, he might be able to talk on that some.
