Anyone know what spring size an Ohlins R+T is for a camber plate order?

[pbondar]

I need to get some camber plates to get my E89 35is with Ohlins BMS MP50 R+T to line up camber wise..

Looked at the Ground Control offering but they are asking about spring widths?

Any clues?

BMW E89 Z4 Camber/Caster Plate Pair

The Ground Control SPORT/SPORT plate, a special version of our camber/caster plates, toned down for dual-purpose cars. Uses a proprietary upper perch which can reuse the stock spring insulator. A work of art, carved from a single piece of billet aluminum. That is the only way to describe this...

Ask Barry@3DM https://3dmmotorsport.com/ would be my vote...or @fmorelli might know off the top of his head.

Ground Control is not the way to go on our cars. Write [email protected] ... tell him I sent you ... he does Öhlins development (with Öhlins USA) and also has better camber plates for our cars (yes I run them). If you need any assistance, send me a PM. Barry is a great guy and knows the Z4 (and BMWs in general) extremely well.

Thnx everyone..I've pulled the trigger on some European sourced camber plates..

I'll pm you Fillipo

Hmm. I didn't use any camber plates on mine and the alignment worked out.

Peter and I basically having conversation in PM. IMHO just the rear numbers tell us it is not a Öhlins kit problem. Both toe and camber out of spec in the rear ...

First of all thanks to everyones’ contributions..

To answer a number of questions.

The alignment shop I use I’ve used several times before on my 20i MSport E89 and they have managed (often with new bushes) to get the wheels to factory alignment spec. They use an advanced machine that’s far more accurate than a laser system. It’s very sensitive system, you could see as the tie rods cooled down (used induction heat to crack the lock nuts) the geometry moving in real time on the display.

I was there with the alignment technician for the whole process and I could see that the rear camber adjustments were at their limit of adjustment.

So seperate the main technician has fitted the Ohlins and the M3 steering arms and the uprated bearings in the steering system plus the m3 rear trailing arm bushes.

Unfortunately I did not previously do an alignment check on the car when it was stock….

I’m no expert on suspension geometry but as I understood it as the car lowers the camber tends to tip inwards?

The alignment tech was probably led astray by me saying that the car was lowered leading him to the assumption that it’s a classical set of lowered suspension syndrome.

The car has no published damaged history..on the UK MOT check there was a history of the owner running tyres to the canvas.

So say the car badly kerbed on the left hand side could it be some bent suspension components?

Here’s a history of MOT checks with worn tyres as an issue..mostly on the RHS (were the camber wasn't as bad) but one on the LHS..could just be poorly maintained, but, tend to suggest that RHS tyre wear was elevated as far back as 2014…

Watching things move due to the heat must have been pretty interesting to watch!

The bottom line is 3 of the 4 corners can not be properly adjusted. Yes lowering the car will effect camber (and of course, the R&T has adjustable perches), but you have both camber AND toe issues in the rear. If you are running the stock Öhlins R&T rear spring, looking at your car photos, I suspect you are at the bottom of the spring perch (adjustability wise). Is that correct? I actually ran a different rear spring than the R&T kit because I wanted more adjustability (same effective spring rate). That said, I've attached a photo of my rear ride height, if you will.

Don't know if he has the time, but I asked @barry@3DM if he could log in and look at this thread, maybe provide some feedback. But 100% of your rear is unable to make number ranges for adjustment, and your left front is off ... that's a lot of stuff missing the mark. We'll see if Barry can hop on and provide feedback. If not I may get some verbal feedback as I'm pretty sure we'll talk over the weekend.

Hi, it’s a mystery but short of stripping everything down I’m not sure what I can do..I’m in the middle of The ‘season’ with runs and outings every few days so pending my garage being built I’m loathe to take it apart at this stage..I can only assume prior to the suspension and steering arm refresh it was out of true…driving wise there is no hint of anything amiss..

I’ve added a shot from my departure today to give an indication of spring heights..

I’m away at a car show now so no rush but anything you / Barry can illuminate would be most welcome

Yes the guy predicted that there was no point cinching the locknuts until they had cooled down…the digital readout ticked away..very obvious example of metals contracting as they cool…

 

[fmorelli]

I spoke with Barry ... he will post up. He had input on how to take care of the rear, etc.

Thank you..I did speak to the UK tech support for Ohlins..they didn't know the E89 specifics but did say that in there opinion the 0.5 ish degree stock camber on the front was in their opinion and suggested between 1 and 2 degrees and at least 2 degrees on the rear ...FWIW

Hi Fillipo, I know this is from and old thread, so I do hope you see this. I've been communicating with Barry at 3DM Suspension, and he said "Unfortunately the camber plates Vorshlag offers do not fit your Z4. The hole pattern in the shock tower is different. To make them fit on Filippos car we had to drill new holes. If you are up to doing this then you need the E82/E9X camber plates"

I told him I've mirrored your suspension build and asked if he has a template from when he drilled holes for your camber plates. He said "I'd have to try to dig up the old info, I've only ever done this on Filippos car. He might have pictures of what we did back in the day. I'll ask him.", so be on the lookout for some communication from Barry.

Thanks for all you do and have done to help make my 35is the best it can be!!!!

FWIW Barry never replied to my email…

This should give you what you need. You can scale this and figure out where the holes are. Simple to make the template.

Thanks Fillipo. I sent Barry a link to this thread. Hopefully he can respond to the group. If not, i'll report back with what he says.

Hi Brian - I'm not sure what you really need. If you order the plates, you can make the paper template so it matches the studs on the plates. Orientation-wise the photos show you the orientation. I believe you have everything you need to proceed. Barry and I did this together - it was not difficult.
