KW Variant Spring Rates? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

smg1138 · 01-26-2015, 02:52 PM

Can anyone tell me what the spring rates are for the KW V1's and V3's? I've tried doing a lot of searches, but keep coming up with conflicting information. Some sources I've read say that the V1 and V3 have the same spring rates while others say the V3 is stiffer. Any useful info on this would be appreciated.

CounterSpace Garage has them listed at 230/285 for the V1's and 343/400 for the V3's.

That clears things up. Thanks!

Those V3 rates should be double checked with KW...I believe they have been switched to the softer rates after an initial run of the firmer 343/400.

Really? Why would they have switched to a softer spring?

***Edit: I just got an email back from KW. It looks like the current spring rate is 230 lbs/ front and 285 lbs/ rear. ***

Beats me. But the firmer rates are used on their KW Clubsports.

Yeah that's what I was 99% sure of and MOST vendors still have the old rates advertised (since that's what they were at first).

The firmer 340/400 rates are on the KW Clubsports which are a good chunk of change more money and without a warranty. But they include topmounts.

Or get RCE T2 Clubsports (built by KW) with a warranty and 400/400 rates.

Yep, that switch happened over a year ago.

Can someone order T2's with staggered rates? I know you offer different rates, but they're square as far as I can remember.

Post up the numbers on the side of your springs.

The 340/400 rates should be 60-something front and 70-something rear.
