For the OP, yellow pace racing and Ceika make "gravel rally" coilovers to the E46. I've a 330i I would want to operate several rallycross gatherings with. Considering the fact that other mods would currently put me in prepared or modified class, I have looked hard at these coilovers.

The billies are reasonably priced, pretty robust (inverted strut style up entrance), and certain deliver the utmost volume of wheel travel of any from the shelf solutions, Particularly when compared with coilovers. My 330i is set up w/ manufacturing facility sport springs & B6 dampers and I've completed three rallycross occasions in it to date. It really is very rigid and slightly punishing by means of ruts, but when I started to have confidence in the chassis & suspension could cope with it (it may), It is really damn pleasurable and I used to be able to set quite aggressive times.
Additionally, it states stretch length with spring is 40-50mm - growth on the spring when tires goes by way of a pothole For illustration; tire drops and vehicles unloads its weight for the spring region.
Numerous yrs in the past I had Many phone phone calls with "PENSKE-RACING-SHOCKS" about my BMW race auto, I'm reasonable sure they will Construct you what you wish.
I'm investigating write-up #three, is there a provision that I don't see that ties what you did into your sub-frame ?
You cant lower the shock much more than its created for. I wouldnt strain that much, just dont have the spring slammed along with the shock at max peak, it places a great deal a lot more strain around the shock and shortens its daily life, and isnt ideal Doing work array to the damper.
Lower the jack to allow the BMW E46 coilovers spring arm to hang. Springs will probably be unfastened at this point in their basket. To set preload and shocks, jack the spring arm back again up until finally the springs on their own are not free inside their mounting basket.
.. Like I said over, zero complaints so far. I'd personally Definitely acquire them once again. There's a warranty, but I haven't got the paperwork in front of me. I will check if I am able to discover the stock top pic for reference, but it'd just take a while.
Damper: The spring both equally compresses and expands whilst traveling on uneven highway surfaces. To regulate damper to regulate spring movement, a one/3 of its piston should really within its overall body housing whilst automobile is decreased with tires on on a flat surface.
Truly Genuinely look at getting some thing similar to the Koni Sports (Yellow / Adjustable) which might be now on sale for twenty five% off. Mix these with the quality lowering springs of the option, the value with springs must are available in at approximately ~$800 pounds.
I've done some activities in my recent automobile with KYB Excel G shocks/struts. These are widely advisable for inventory class and held up good as a result of some quite rough things.
Great tune experience heights both entrance and rear; then you'll want to get wheels aligned and corner body weight balanced by a certified know the way store; and they're couple of and much involving in a few areas.
I don't love the OEM BMW spring set up on any of those hugely promoted consumer package variants available - its just for rear overall body drop uses.
