John: Elaborate on you background please.
Started in karts in 1979 and then went on to Formula Ford. Started FF with the Russell School's rental program in 1980. Was the factory driver for the Viking Formula Ford team in 1981 and 1982. Rookie of the year in my region in '81 and then Nor Pac Formula Ford Champ the following season. Drove Pro Super Vee in '83 and '85, with a year of Russell Mazda Series in '84. Was asked to race in what is now Indy Lights by an established team in '86, but the financing package just did not come together. Tested a stock block powered Indy car for a rookie team in 1989, but the team never put it together.

Gratzy and impressive.
So, I should assume the R's you sold me are shot from heat cycling right?

Seriously though, Tim, you should think about doing the RSR crossmember/rear carriers and the mono-ball control arms. I think these are the basis of curing the handling problems with the turbos. Then an awesome alignment. BTW...working with Cary reminded me of working with Carroll Smith.

I already have Cary's solid arm mount disks (replaces the dognut in the rear). What else do I need for sure?

I've said it many times before, Cary is the best!!!
Cary, is my car next?

I think it would really be fascinating to see a GT-2 done by Cary and compare the differences...

John, how is the ride quality with all of the rubber removed on the suspension attachement points?
1. Can you feel a qualitative difference?
2. Does the car get resonance through the chassis on rougher roads?
Thanks!
P.S. I had a 993 C2 that ultimately ended up with close to what you've done to your car. Dropping the suspension on these cars without changing hub carrier centers can sometimes cause side effects.
And lastly for all of us here. How about some pictures?

Will run the car up on my local mechanic's rack over the next couple of days and post the pics I take.
Cheers...

One advantage of the GT2 is that many of the Motorsport parts adapt much easier to the RWD platform.

John's car also has the RSR front cross member which raises the roll center and modified rear RSR carrier supports... I think that really helps when you have the ride heights most of these cars are using... If you were to just measure the supports to the ground, Johns car it won't reflect exactly whats going on because they have been moved up higher into the chassis. This is where a lot of the numbers don't make since when measuring from car to car. These units on a GT2 are in a different place from a stock turbo so if you measure from the sub frame of a GT2 and a TT then measure from the wheel opening to the ground they won't be the same.... On John's car those same numbers would be different again. When doing John's car I wasn't concerned with where the frame was to the ground but rather the roll centers and how the the roll couple correlated to the Center of gravity on his car at it's weight and weight distribution. I know it sounds like a bunch of babble but there are some sweet spots on these cars and they do vari depending on a lot of things. The exact set up on Johns car wouldn't necessarily be the sweet spot on a lighter car or a car putting down different HP. I think his set up is much more the right direction and I still feel there is more tweaking that can always be done and then as John says, he likes a bit more oversteer than most which is fine if you have the driving experience he has... for others I might stay without as much oversteer ... but the fun thing with John's car is this... remember that old video of the Ruf Yellow bird on the track in Germany doing those oversteer burn out exits off 70 mph turns?? well you if you want, it's easy to do that with Johns car if you over cook it just a bit with the psm off. The difference being, it feels like all four wheels are lit!! Oh btw... again... sorry about your brand new tires John .... but it was fun... Honestly you can throw that car at a turn.. think you know you're going off the track and still save like you never missed a beat... I didn't think a turbo would work like that... but I was wrong...

I guarantee you all four wheels spin in a turn when you defeat the throttle body shutdown.
Oh .......... you did redrill the frame to lower.
