Precision EFI and Thunder Products Clutching

[SRmissile]

Big thank you to Precision EFI and Thunder Products for waking up my ‘18 LTX LE.
Stage 1 flash, 911 clutch cover, BV weights, holeshot helix, rollers and springs. Ran 189 kph on gps this weekend.... what a rush. This setup gives amazing and instant acceleration. Might have got more out of it but I ran out of nerve before I ran out of gear.
All the guys at Precision EFI and Terry at Thunder Products really know their #*$&@. Great companies to deal with with Fantastic support.

Hi BBY,when you had your EVO stage 4 tune and ran STM ramps,do you remember where and how much weight we had placed in each area? I remember the mid empty,tip loaded and heel light.

Ya they did terry,i did want to ask you when we talked,what is the diferance in thousands between the outside dia. of the coller which is what the roller rides on,and the inside dia. of the roller? My stock roller and coller that I removed and looked at,seemed like there was a lot of room between the two,it appeared to be up to maybe .006 thou. now I should of measured them when I had them out,but got side tracked. Terry do you have any idea?
