John Lane,

You broke the 12mm ARPs? Interesting. That is what I have been using...the Camaro/Firebird studs...they have the right knurl for the hub of the Mazda Protege hubs I've been using and work with the RX7 rotors. I just turn off a few threads.

You have me thinking, as the Protege had no issues with this setup for 5 years, but it had half the horsepower I have now.

Were you using hubcentric wheels or were you letting the lugs take all the force?

Hmmmm.

Thanks for any insight.

Eric

Lurchie, the dyno sheet I saw for that whacked out Dourvin V6 with the big T4 showed 515 ft/lbs at some paltry rpm.
And at low boost setting.

Sheesh, glad he had all the internals from JVAB Imports!

Can a guy still get in on these spacers? I need 4 x 4 1/2 pattern, not sure about the other dimensions...
