KW V3 swift/hyperco spring conversion? Spring OD comparison?

I am running KW V3s and having issues with inner clearance on the front, my tires are rubbing the springs.
I wonder if Swift or Hyperco springs have a smaller OD so that I can gain more clearance from switching over.
Thank you

What is your wheel/tire size and offset?

Is it rubbing the spring perch or spring itself?

Don't bother changing the springs as the KW shocks are made to work with the KW spring "rate." Get yourself some wheel spacers (with either extended wheel bolts or upgrade to studs) and you'll solve the problem. It's much cheaper and tons faster.

A lot of guys end up needing a small spacer. 5mm is ofter enough to gain clearance for the coilover. If you have clearance between the wheel and fender/quarter panels you should be able to easily correct your problem. HERE is a link to my spacers of your E46 M3.

Depending on the wheel size, that might not work actually. Seeing that the OP has an M3, he's probably running something around a 18x10 I would imagine, probably a low offset. A spacer would do the trick, but to make up for how much wheel is sticking past the fender, you'll need to add camber, and then we're back to square one. Adding in a linear spring will help, and I've had multiple customers change to swift springs to avoid clearance issues on KW's due to their beehive shaped spring.

OP, If you need help, let me know, we're a Swift spring dealer
