Spring Rates
 

I'm looking at getting new suspension for the ti, as it's got over 200k on stock suspension...
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

Anybody?

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?

Id say go with like 300lbs in the rear and 450lbs in the front or something along those lines.

I'm not that educated on suspension though. Don't go buying anything. I just know rear should be less than the front.

Will keep that in mind, thanks!

Figured I'd try to point you in some sort of direction!

Thanks man, appreciate it! Anybody else have some spring rates they like for a stock 318ti?

Nothin from anyone else?

Go to h&r website and read about spring rates. And maybe it will answer your questions

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.

Awesome, I want something more on the stiff side for daily, so ill keep that in mind. Thanks for the helpful advice!

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.

Okay, so I'm thinking I'd want something a bit softer cuz I'm not hauling dogs lol. Will keep that in mind. Seems like somewhere around 400/600 would be a pretty decent setup then

Anybody know if the spring rate should change when you change spring manufacturers?
