new suspension?

[Cellardoor]

Hey guys,

so im thinking about getting new suspension for the M soon, the current suspension is getting a little sloppy and i think it is starting to rub on one side. so im asking what would be a nice set up, i thinking a race set up since comfort isnt a concern for me in the car so anyone with any advice of companys and mayb prices i would appreciate the heads up ! thanks in advance!

ps sorry if this is worded poorly its 3 30 and i have been up since 7 haha.

As "X" mentioned they're all good but shop closely re: Konis. They make a couple of different grades and the "base line" units are a glorified stock units (just compare shaft/piston size) I had Konis & just replaced w/Bilsteins sports and the diff was night & day.

coilovers or bust.

i really like my bilstein sport shocks with h&r sport springs but if i had to do it all over again i would go with a nice set of coil overs. probably from ground control.

[DEATH2000]

Coil overs would be kool. I have Konis and there pretty decent.I like em.

I love my Bilstein Sports. I can't imagine what the Bilstein Race setup would be like though... :drool

Ground control coilover setup with all the supports, etc. Like rtab shimmy's. You would also need camber plates, but thats ok Man that thing would have ///Mazing handling, ok so that was corny lol.

i wish i spent the extra coin and didd that

yeah i think for the most part people who got shocks and springs wish they woul've just put in a little more money for some coilovers. I'm really happy with my Bilstein sport/ H&R race setup. but camber plates, adjustable control arms are a must. and yes you should definitely replace the RSM's FSM's, ltabs, rtabs and so on and so forth

Sorry to hijack we should get storamin back on here.

coilovers + corner balance

what do you mean by corner balance?

Basically you can adjust your suspension ride height enough at each corner so that essentially each corner is acting as if it's holdign the same amount of weight. You want to get a perfect balance between all four corners. Some race shops near you should have the scales. Have them do it, or if you got a lot of time on your hands and feel liek havign some funw ith some friend go ahead anf borrow/rent them from them.

Think of it this way. There's no way all four corner of your car weigh the saem at each tire. So you put all four on the scales and find the weight at each corner. I've never doen this but you need to essentially take all the numbers and calculate out what weight should be added at each corner adn what weight should be removed at each corner to get them all to be the same. The catch is you never add or remove weight. Instead you hypothetically find how much weight must be removed/gained. Then you slightly adjust the ride height at the corespondign corners.

Each corner acts similar at it's caddy-corner (front left has same weight characteristics and rear right).

So let's say your front left and rear right need to pick up some weight and your frotn right and rear left need to lose some weight. Essentially (if i got this right in theory), So if you lower the ride height a hair on the front right or rear left, then there's less weight on both of those and more weight balanced onto the front left and rear right. It's hard to see in writing but it makes sense if you really think about it.

A good analogy someone told me long ago was imagine a giant box that four people of equal weight/muscle/height/build were carrying. Each person is hold a fourth of the weight. If the back left corner were to lower just a little bit, that would put more weight on the back right and front left corners. I was always a little confused as to why the back left corner never gained weight, btu im assuming it has a lot to do with the rigidity of the car. Thats why sometimes you see a car that could essentially drive on 3 wheels (albeit not well).

I don't have the exact science down and i've defintely never had personal experience with it (damn h&R/Bilstein), but as soon as I get coilovers it would be the first thing i'd do.

I'm sure I missed/confused a few things there, but I googled this and I think it should help clarify things: http://www.scottgood.com/jsg/blog.ns...ks/SGOD-6B9PFW

thanks for explaining. I have coilovers on my e30 and couldn't be happier! Find out what the manufacturer recommends for your type of driving in terms of spring rates and add 50lbs to make it a little edgier. Mine is not too ridgid and handles like it is on friggin rails!
I am corner weighting mine as soon as i get a chance to see the difference between stock and m30 swap e30s as well as dial in my suspension.
