I bought a rear shock that was a left over from the martin cardenas yoshimura days. The shock isnt labeled,not sure if its anything special,or team one off part. My last race on it a suspension guy that was helping,maxed it out on the spring.Said I need a 9 1/2 spring on it? Are springs interchangable with other brands? Never messed with springs before ,so don't know? Normally always bought new to my weight
Ohlins springs are good quality and are sized for the shock, easy to get or trade for. The race spring may be an RR spring, what are the numbers stenciled on the spring?
I honestly don't know? No markings,all I know is it came outta some Yoshimura Cardinas sell off.I got his old bodywork,and rear shock
You can buy nearly any size/rate spring here: https://eibach.com/us/c-103-motorsport-springs-accessories-race-spring-system-ers.html
