Drove my T4 today at our club race. All I can say is that it's an awesome car. Coming from a T3 2011 with 2012 chassis and topdeck, this car was faster for me.

It's was more stable, easy to drive and had plenty of steering The track I drove on was low - med traction. We drove with ride 32 tires (control tire for our nationals and ETS). My car was tail happy in the morning but after a few changes I had a very good car. My friends that were Coming from the T3 2012 copied their setup on the T4, but that wasn't perfect. After they had driven my car, they started to copy my setup And they are better drives than me (top 5 guys from Belgium), so they what a good car should drive like.

how did you find that diff weight? did you use any other or just went with that weight?

I build the car completely like the kit setup and went from there. With 700 the car was too nervous on turn in and less predictable. The 2000 oil calmed the rear down off-power and made it more predictable.

What did they have different on their setups that did not work?

Short, low front link and a long rear link. I tried the short front link and my car had too much roll in the front. The rearend was less predictable and my overal steering increased a little imo. The car was more stable with the medium front link. And after adding a 0.5mm link, the frontend was a bit calmer. I could push the car pretty hard and it was fast in the chicanes.

I should have tried a 2mm shim on the rearbulkhead, but 1mm was also great
