No....950R or even the early 960 using the old 1/8 offset rim....Serpent release the OS2 hub and changed to the current wheel offset. If you need something for 950R you must get those OLD offset rims....mainly are the BBS spoke looking neon yellow thingy.
You are correct...lower the number, softer they are, but the tire wear are faster too...
Depends on the track condition...fully well prerp track, you can use something 35/35....if lower traction, you will drop down to 32s or even 30s...but there are just WAY too many combination that you can use depends on the track condition, car setup and bodies...I used alot of 35/35 with sometime 35/37 and 30/35.....and because of that, I can no longer afford to race this class...LOL
