Any recommended spring rates? I drive mountain roads everyday so would like something fairly stiff for spirited driving, but also it's a daily driver not a track car. I'm looking into the BC Racing coilover set up and just want to make sure I get the correct spring rate for some good fun and all around driving | | | 06-15-2013, 02:47 AM | #2 | Member Join Date: Jan 2013 Location: Felton Posts: 32 | Anybody? | | | 06-15-2013, 11:33 PM | #3 | Member Join Date: Jan 2013 Location: Felton Posts: 32 | Or how about the same spring rates as a 91 318is? I've also heard about running different rates in the front than the rear, so would that be the same with the IS? | | | 06-16-2013, 01:14 AM | #4 | Senior Member Join Date: Sep 2011 Location: Florida Posts: 404 | Id say go with like 300lbs in the rear and 450lbs in the front or something along those lines. | | | 06-16-2013, 01:16 AM | #5 | Senior Member Join Date: Sep 2011 Location: Florida Posts: 404 | I'm not that educated on suspension though. Don't go buying anything. I just know rear should be less than the front. | | | 06-16-2013, 01:50 AM | #6 | Member Join Date: Jan 2013 Location: Felton Posts: 32 | Quote: Originally Posted by Breticus I'm not that educated on suspension though.

And maybe it will answer your questions Sent from S4 on tap talk | | | 06-21-2013, 10:11 PM | #11 | Senior Member Join Date: Apr 2007 Location: Elizabeth City, NC Posts: 3,877 | H&R doesn't publish spring rates and you don't want what they recommend anyway. I currently run 400f/600r and I like it for daily/autox/track. It's probably a bit on the stiff side for just a daily driver. However, spring rates are really personal preference to the way you want the car to handle. Just pick something to get started and then pick up used springs and swap them out to test. __________________ ~Dave~ 98 328ti Morea Grun slicktop 11 128i space gray slicktop 13 JGC WK2 Deep Cherry Search | RealOEM | | | 06-21-2013, 10:20 PM | #12 | Member Join Date: Jan 2013 Location: Felton Posts: 32 | Quote: Originally Posted by spidertri H&R doesn't publish spring rates and you don't want what they recommend anyway.

Thanks for the helpful advice! | | | 06-23-2013, 01:56 AM | #13 | Senior Member Join Date: May 2013 Location: Morgan Utah Posts: 214 | I have been working with Ground Control on a full coilover setup and they are recommending 500 ft, 700 rear, rears will differ from regular springs since a coilover. I am setting the car up for site seeing, grocery getting, HPDE, TT and hauling our 230 lbs of dogs in the back seat......some compromise had to be reached. | | | 06-24-2013, 09:40 PM | #14 | Member Join Date: Jan 2013 Location: Felton Posts: 32 | Quote: Originally Posted by raamaudio I have been working with Ground Control on a full coilover setup and they are recommending 500 ft, 700 rear, rears will differ from regular springs since a coilover.

Will keep that in mind. Seems like somewhere around 400/600 would be a pretty decent setup then | | | 06-28-2013, 01:37 AM | #15 | Member Join Date: Jan 2013 Location: Felton Posts: 32 | Anybody know if the spring rate should change when you change spring manufacturers? | | | | | Currently Active Users Viewing This Thread: 1 (0 members and 1 guests) | | Thread Tools | | Display Modes | Linear Mode | Posting Rules | You may not post new threads You may not post replies You may not post attachments You may not edit your posts HTML code is Off | | | |
