I'm doing a 3.3L Subie conversion with a WRX trans using Ian's kit. Not sure the 90 lb rear springs are going to cut it, and they need to be changed anyway. What spring rate would be best? 250 hpish flat 6. Weighs about 350 lbs I think. Don't want my teeth rattled out, just want them to be strong enough for the job. Maybe the stock springs are OK I just don't know.
Build thread coming soon!~ |

I think 200-lb. springs would be nice, paired with 21-mm torsion bars up front. That's my setup with the LS1 V-8, about the same weight as yours. I've get Koni yellows set on full soft, and the ride remains pretty civilized, and I've yet to bottom out the rear suspension even at a slightly lower-than-stock ride height.
