More 135i/335i Suspension R&D - E9X M3 rear camber link and damper

flukey · 02-17-2009, 10:35 AM

How about developing some custom links for the front of XI vehicles?

Can be done, but will cost $400-500 per pair and in quantities of 25 pairs minimum. That is not even counting the contract engineering time.

will these work on the 135 as well?

Yes, it will!

Finally! All R&D for the E9X M3 rear lower camber link is all done. The complete kit will be a true bolt-on replacement for your E82/E9X 1 and 3 series.

Dampers and coil over style springs with height adjusters will be optional, but highly recommended for easier installation and ride height adjustment.

So really I should just need to change the springs?

and 1000s in the back? Seriously!?

Do share some photos of your new Stoptech brakes!

We have done so much testing to arrive at that rate. Depends on what type of your driving you do mostly with your car. Rear subframe bushings is highly recommended for spring rates over 600 lb/in.

You may also want to consider going to the M3 front and rear control arm links to take some of the suspension link bushing bind out of the oem 335i suspension.

Very exciting news. Great work guys!

HP Autosport · 03-31-2009, 01:07 AM

Please PM, email or call us if you have questions regarding the M3 rear lower camber link conversion kits!

HP Autosport · 04-07-2009, 01:56 AM

Both AST and Koni in S/A or D/A and AST triple adjustable coil-over kits are available now M3 rear lower camber link conversion kit.

Ask us about our custom Swift spring upgrade to make the AST and Koni coil-overs even better.

Malek@MRF · 04-07-2009, 04:50 PM

On your website for the rear kit, when you add the "Koni single adjustable" option, is this for the front AND rear and features dampening adjustment with height adjustment?

I would like to know.

Thanks in advance Harold!

The Single Adjustable option for Koni is just the rear M3 style damper and Swift coil-over spring only. You will need to select the coil-over option to purchase the complete front and rear kit. Please PM, email or call if you have other questions.

Quick question: if one were to completely convert to your M3 front and rear suspension components, how much weight would be shaved? ~10lbs?

Not counting the weight savings of the Swift coil-over type spring is about 8 lbs. You will be replacing the rear oem springs with our custom Swift springs, there is another 7-8 lbs of saving, this is just for the rear.

Weight savings just one of the many benefits of the complete conversion, not to mention better bushings with less deflection with the M3 control arms, better mounting for the rear damper with much less deflection and quicker damper reaction time.

stressdoc · 04-08-2009, 12:41 PM

Weight loss in 'unsprung' suspension parts is very important for performance. The aluminum M3 parts weigh about a pound or two less per part. Much greater reductions are possible in the springs and dampers. Brakes (caliper & rotors) are another opportunity. The biggest reductions in unsprung weight are in forged rims and lighter non-rft tires. In total it is possible to reduce unsprung weight by 130lbs or so.

But clearly the biggest effect of the M3 parts is the reduction of uncontrolled movement. Imagine a gymnast performing on a balance beam that is a rubbery pipe instead of a solid wooden piece.

Turner MS takes this as far as offering solid subframe bushings and damper mounts. No way those would be useful for a DD.

IMO the E9x is especially problematic in that the bushings and other components of the suspension are required to deliver a luxury car ride on rigid rft tires.

The total M3+ package that Harold et al have put together is quite amazing.

I like the toe-link. When will I be able to buy one?

justin

Edit: I mean two

GreenPlease · 04-27-2009, 09:17 PM

Harold: could you PM me an estimate (sans labor) for a complete M3 suspension conversion (front and rear)?

I only plan to track the car 1-2 times a year so... I think the Koni single adjustable shocks?

bestsw20 · 04-28-2009, 12:01 AM

When will these be available to the public? and how much??

bestsw20 · 04-28-2009, 01:15 PM

sounds good, but how much performance will we pick up with this? I have all the m3 parts on my 135i already, this is the last piece of soft rubber that I want to change.. just want to see the difference that it will make..

HP Autosport · 05-08-2009, 01:06 PM

Toe links are being field/track tested.

Great, Harold....I'm going to have to add this to the order, too

There was a significant amount of engineering and analysis that went into this product and no compromise were made. These links far exceed the M3 OEM quality and performance. The product is going into field testing so expect this to take several weeks.

In the mean time if you want to set then PM harold.

You see some pics in few day with custom KW / M3 suspension conversion. I already have them installed.

Based on this, would you say that this would also be a good mod for an e90/92 M3?
