We will be modifying the attachment points of the control arms, going to a coil over shock, work on recessing an adjustable front sway bar into the underside of the subframe, and then possibly recessing the modified stock subframe into the car approximately 2".

Hyperco does carry coil over springs in 10" up to 900 lbs but they are 2 1/2" I.D. I imagine 1/8" shouldn't be a big deal. Thanks for letting me know.

That will definitely be a piece of the puzzle Greg, at least for the upper arms, but I've heard that the lower arms get raised upward 3/4" and outward 3/4". I'd like to see this all drawn up and explained to me. In addition I think that this will be a pretty cool little educational project during the off season..

In the mean time...After my last Thunderhill track day in April I changed my front alignment settings and raised my rear roll center by raising the watts pivot. I couldn't wait till July 1st for my next track day so I will be heading back to Thunderhill on May 19th. Target lap times to be in the 2:04's which means I will need to shave at least 2.5 seconds off of a best 2:07.4 last time out.

Oh, and the LS Vince posted, dont believe it. :lol:

Sounds like an awesome plan! :bow: And that lexan + decklid are going to be sweet.

Thanks Sieg, I've scrolled over Dave's stuff quite a few times. I'm pretty sure we will be doing the Guldstrand mod but who knows what else Vince has up his sleeve. 7 months is a lot of time to get ourselves into trouble. :unibrow:
