A little less steering on centre btu more mid-corner/exit steering. We also had the 2 screws removed from the front of the spur gear portion of the upper deck - both changes provided more overall grip but did make the car suffer slightly through chicanes. The test was done back to back with-in 15mins(both times on new tires) so we were able to eliminate the track changing as a variable.

Also, I think this change helps when running a front diff as it keeps more load on the inside tire when driving off the corner. Some of the Xray guys switched back and forth between the spool and diff with mixed results, and I think it might have had more to do with the front end flex(split blocks and cut deck) then anything else.. Most were running 1 piece front blocks. Back home we tested both a spool and diff THOROUGHLY - what we found was that you had to committ to this change, and by commit, I mean change the rest of the setup to work with it. This is a common mistake I see some people make at big races, or any race for that matter. I believe the reason our car was one of the better T4's at the race is because we tested each one(spool/diff)and made the necessary changes to the car that suited both. When testing was completed, we could honestly say we gave both a fair chance. For us, what made the diff work best were front split blocks and the cut upperdeck! We had more front end flex on our car which provided more grip to the inside tire and the result was better drive off the corner. Now, combine that with the better turn-in and increased corner speed from the diff (advantage over the spool), you have the best of both worlds!

Corey, did you only use the option arms in mod? If so would you mind explaining what the difference was?

I heard of a couple people running the solid (one piece) suspension block in the (forward) rear, were you guys still running the stock T4 split blocks?

Thanks!

I think you're going to have to start an "Ask CoreyW" thread.

I bug him to race with us all the time. He's probably tired of hearing it.

Thanks guys, really.

I think I will keep my help focused on this thread and its followers for the time being. I do have a life outside this forum afterall

Please keep in mind, there isn't really anything extremely special about Andrews cars, it just comes down to attention to detail and being thorough with EVERY aspect of the car. If you don't have the basics down(prep), you can't properly test setup changes and you definitely won't know their true effect. Lastly, I am lucky to work on a talented young drivers car, because sometimes, the car isn't as good as it looks, he will just wheel the shite out of it regardless. At the Snowbirds I was fortunate enough to get it right where HE wanted/needed it..

As for wheeling an Xray, I just might, but only to improve our testing program. I use to race years ago, but now I focus on my real car instead.

Corey, thanks for posting the set up sheets sir. And congrats to you guys on how well you did. You, Andrew, and Ian have always been great to talk to the few times I have raced with you guys.

Did you cut the stock upper deck, or the thin one? Assuming you cut the stock one, would using the 1.6mm top deck give you the same or close to the same result?
