Yup. Tekin RS.  With Jaco foams. I don't know the diameter of them off hand.  I did go get myself one of those digital calipers that are on sale at Can Tire though.

Auto, if you go to Gearchart.com, you can print off rollout charts based on your tire diameter and spur gear size.

Well, I read through this whole thread again, trying to figure my rollout still. I just dont want to buy a bunch of pinions and spurs I wont use.

I ran a 13.5 with 78T spur 24t pinon and 2.18in tires for a roll out of 53.54
with 2.5in tires you could use a 78t spur and a 21t pinon for a roll out of 53.71 as your tires wear down you will need a
larger pinon. My car was more the able to run under 12sec laps. but the driver was not

Hope it helps
