Cool. So if an aftermarket link like the tarett clears my OZ wheels, so will the TPC.

While I had planned to write a more complete message, this thread seems to be a good opportunity to add another account that echos TPC notes.

Quick bit about me: After years ago being heavily involved with DEs and then moving on to own and play race cars while traveling with a professional team I have taken quite a number of years away from being at the track. Recently I have just gotten to know TPC after they have setup my GT4 this season (street/track alignment, Cantrell roll bar, harnesses, brakes, etc).

This past weekend I was at Watkins Glen and paddocked with Tom. Even though TPC has offered to let me try the DSC before, I had declined as I wanted to first get a sense for the car with making adjustments one step at a time as I got back involved. For the last session of the day I asked Tom if I could take him up on the offer to try the DSC to see what the difference is.

Much like OrthoJoe's notes and true to TPC's description the DSC was certainly noticeable... Nose dive was greatly reduced and the car did feel more stable, specifically under heavy breaking.

Reading the list over time I have seen a number of threads regarding a reduction of some number of seconds that the DSC may help achieve. While I believe that DSC will help in lap times, I think this may be missing some of the point as a lap time itself involves quite a number of factors. The increased stability is noticeable and could certainly contribute to such. In my case, the largest takeaway was a feeling that I could manage the tires grip better, particularly under breaking. For my data logging, I can simply say that in the last session where I used the DSC I did not have enough clear track or time to get what I would believe to be a valuable overlay for comparison but will be looking more closely at this in the coming days. Regarding purely lap times, I can say that my times were very similar between stock controller having open track, and using the DSC while managing to get through quite a bit of traffic. Overall, I do believe that the adjustments that the DSC made did provide increased stability that was valuable.

I hope to get some useful data overlays between my sessions stock and the one I used the DSC to share. However, I can say that the DSC came home in my car :to_order:

Nope. I didn't want 10" because oem is 11". I got 19x11 et50, and it fits just fine with the tarett links. You have to call Damon to order the 19x11 wheels.

Joe, my question to you is, now that you know about the problem described by BGB, have you done anything to your rear suspension, other than toe links to dial in more camber?

Originally Posted by orthojoe (Post 13396888)

Yup. It's because they won't fit with oem toe links. Need to have aftermarket ones.

The product is a legitimate upgrade and is staying in my car. You really don't need to be a pro to feel the difference, it is that big. FYI, anyone in CO is welcome to try my unit at HPR if they like. Swap takes 5 min.

Swapping that inner rubber control arm flange for a Cup style monoball one fixed everything for us.
