Foams- Preferred Traction Compound and it IS STILL VERY MUCH LEGAL is Paragon. I have never heard that it pulls up the glue that holds down our carpet. TQ products are the second best alternative that I have tried although I am hearing good comments about the Corrally Jack the Gripper stuff and the new CS stuff as well. At big races I am down to 8 min on with 15min off for Paragon but for club races I'm now at 15min on and 5min off. TQ stuff is double for these values and you don't get as much traction. You also don't get as much consistency with the car's response as you do with Paragon. Paragon just makes the car HANDLE better and more consistently than anything else thus far. TQ 8+ and TQ Mod are the second best and do an admirable job. If you run at a track that allows Paragon, and many still do, then run Paragon but if you have to use something other than Paragon then use the TQ 8+ or Mod stuff and double my figures for paragon.
