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!~ |

Chris,
I'm only looking at a 2.5L SOHC Subie with Ian's setup, and I'm seriously rethinking going back up to 140LB springs from the 90s I currently have. I'm searching for a spring rate calculator now, but share what you find on your end if you come across one that satisfies our setups. Dave |
