Suspension/Ride Height Thread

Post by bmwm3n528 »

This was popular on an E30 Forum, and gives folks (like me) a chance to see the ride height/look with different springs/wheels/etc.

Please include:

Model/Motor
Profile shot of the car
Springs
Shocks/Struts
Other Suspension modifications
Wheel/Tire size


Thanks!

M535i/M30B34

Image

King lowering variable rate springs. 20mm drop on M-Technic = 40mm drop on standard = 5mm drop on Euro M5. Standard 10mm rake forwards maintained.

Koni Sport adjustable dampers set at 18% hard all round. Stock 19/15.5mm anti-roll bars. No camber correction. Spacers in RHS struts front and rear to correct for RHD lean. Car sits perfectly level side to side with no-one on board. The best that could be achieved with the standard thread lengths. Urethane radius arm bushes. All other bushes brand new but OE.

BBS/BMW M5 wheel 16x7.1/2 et20 match mounted to Yokohama AVS ES100 in 225/50-16 @ 32psi all round. Stick on hidden wheel weights. Rubber valves. Locking wheel bolts with dust caps. No spacers, no hubcentric rings & no wheel has more than 15g stuck at any one location.

Pictured here fat with fuel + extra 9 litres in spare wheel canister.

Could you guys re-size your pics? I'm on broadband and it's still taking ages to load.

Good idea, forgot about this.

If you wouldn't mind including distance from fender lip down (specify M-Technic arches and non-M).

Resized, hope that helps

I have used Bavarian AutoSport to purchase much of my suspension stuff, namely....

Bilstein Sports
IMAC Camber Plates
IMAC Adjustable Trailing Arm Bushings
Racing Dynamics Adjustable Swaybars - Front and Rear
Racing Dynamics Strut Tower Stressbar
Lower control arms - new, stock

I also used the Bilstein sports and Bavarian Autosport lowering springs on my '87 535is. Don't have any pictures yet but I will post as soon as I have some

Yeah, Definitely post some pictures...Have some BavAutos, contemplating using them or replacing with the ST springs.

The BavAuto Springs are definitely not for tracking, to soft. They give nice ride height and are a little more aggressive than stock. Mostly just a comfortable ride. For more aggressive ride I would recommend H&R's or Eibachs.

WOT, but here's some stuff (suspension and otherwise) the E36 gets tomorrow. The weld-in bits I'm not doing myself, of course.

Should make for a pretty, umm, firm ride when coupled with the PSS9 coilovers (which are really quite nice in the ride deparetment). With the exception of a few minor bits, the only rubber under the car will be the tires. The solid motor and trans mounts will go in later; they're not here yet.

Oh yeah. I've heard all about their springs with E30s, and they definitely don't have any sporting credentials...Thus, the reason I'm still on the fence about installing them.

Whoops!

Missed it.

ST claims a 1" drop on front/back. That seems lower that that!

[quote="bmwm3n528]ST claims a 1" drop on front/back. That seems lower that that![/quote]

John's car might be parked on a slight hill there and held by the handbrake. That will be pulling down the rear suspension a bit ofcourse, so allow for that possibility. Allowing for that, his car looks to be at the same level as mine which is ~40mm lower than stock Euro springs and ~20mm lower than M-Tech springs. So yeah, if you're comparing to stock springs, it's much more drop than 1" all round.
