M-sport springs v EPK springs
I have read a lot that guys have replaced their m-sport springs with EPK springs with almost no noticeable drop.
Both springs are linear and spring rates are almost the same as well. ZSP Front: 145 lb/in Rear: 460 lb/in EPK Front: 148 lb/in Rear: 456 lb/in Just wondering what is the reason for changing from m-sport to EPK. Is there actually a difference in performance? I dont want a big drop so the EPK appeals but is it a worthwhile performance upgrade? |
