Any have one done? Weistec kit? Other options? Current transmission is fine. But I want to bulletproof it for more torque

 

talk to @brutus_tx ... he knows guys that have done this and discuss this sort of thing routinely on off forum message boards ... also @brutus_tx is immensely knowledgeable and experienced on this platform and has helped move it forward over the past several years

 

Will Do. Have read many of his posts

also of course @JesseB will be a wealth of knowledge for you

 

When I go built I'll go with this shop. Very knowledgeable guys, they build a lot of the C63 transmissions.
