I need advice on alignment set up for my 95 M3. I have a big front end push on corner entry, mid-corner, and corner exit. The stock front alignment is just not cutting it...

Current set up:
TMS Bilstein Shocks/H&R Sport Springs
Stock Sways
TMS Rear Camber Arm
DS1's with 235/40/17 RA-1's

I am going to purchase camber plates for the front, leaning towards the Vorshlag plates after reading some good reviews.

Any alignment recommendations for when I do install the front camber plates?

Thanks for your help.

get some sway bars and negative camber as you plan on doing. Those two things and non staggered wheels make a ton of difference for getting rid of understeer. I'd also strongly suggest H&R Race springs over sport, even though some of people may tell you otherwise. I've used both on the track.

Was there a BIG difference in performance from the H&R Sport to the H&R Race springs to make it worth the switch?

Can anyone with this set up provide me with there alignment specs?

Thank you!

I have a stock suspension but for RSMs and RTABs. I cannot get any decent camber in the front at all, but I was AMAZED by the difference when I went to zero toe in the front. The front end worked much better than before. The car is a smidge less stable on uneven pavement, but nothing scary.

Are you doing autox, track or both? The alignments people on here prefer differ depending on the application.

Vorshlag camber plates set to -3 to -3.5 degrees and a stiff front sway bar (25mm or bigger set to stiff) will keep your front end planted.

Front toe set to 1/16" toe out. Rear toe set to 3/16" toe in. Rear camber 1 degree less than the front.

You will love it. :D

I have the Vorshlag camber plates and they make a world of difference! Loosen three nuts and slide them all the way in for -3.5 degrees or all the way out for -1.75 degrees on the street. I run -2.00 degrees in the rear. 0 toe in the front and 1/8" toe-in at the rear.

What caster setting are you using on the vorshlag plates?

What caster setting are you using on the vorshlag plates?

There's only three settings for caster and they come from Vorshlag pre-set to maximum caster. I left them there, as recommended.:cool

Most road course drivers like the added caster that the rearmost position offers.

Autocrossers can see more front camber with the middle caster setting on our E36 plates, where they can get to -4° to -4.5° up front (or more depending on ride height) using coilovers. The circular strut tower opening makes this relationship - max caster tends to reduce max camber on coilover cars.

We tend to run our Solo M3 at -4.2° camber up front, but that's a bit extreme for some folks. Tire wear and pyrometer are very happy, though. With OEM style springs the large diameter of the spring and the strut tower enclosure limit max camber adjustment to -3° or so anyway, and in those cases the max caster setting isn't limiting camber range.

In 2 weeks we have another practice event we are hosting. We are setting up a skidpad (1 of 4 courses or elements we always lay out) and will take more data with some different camber settings, checking pyrometer temps and data logging times/grip. We are working on a tech article about this subject, which we'll post here in the track/autox section.

Say you're running reversed strut hats with ~-3 degrees of camber with the OEM springs at stock ride height. At what point does wheel width , assuming proper offset/use of spacers "usually" (obviously slightly different for each car) start to have issues. I'm specifically looking at moving up from the oem 7.5's upfront to 8.5's.

I thought when you moved the camber plates that the toe settings changed? Please correct me if I am wrong...

Terry,
Do you have any track settings for your plates?

I will be contacting you shortly to place an order.

Vorshlag camber plates set to -3 to -3.5 degrees and a stiff front sway bar (25mm or bigger set to stiff) will keep your front end planted.

Front toe set to 1/16" toe out. Rear toe set to 3/16" toe in. Rear camber 1 degree less than the front.

You will love it. :D

Thank you joenationwide I will try those settings and let you know how it goes...

I would highly suggest sway bars. UUC motorwerks has very good and dependable sways. At the least start with a front sway bar.

I thought when you moved the camber plates that the toe settings changed? Please correct me if I am wrong...

That is correct but the beauty of it is you can have two settings for camber and have your toe set to suit each setting. For example for the street I run zero toe up front and whatever the least amount of camber I can get with the Vorshlag plates at my ride height which turns out to be about 2.5 deg negative. At the track I slide them in to a marked setting I have and I run toe out at the front tires.

I happen to have a used UUC front sway bar that I no longer need. :D
If anyone is interested send me a PM.

Carlos.

Thank you for the input guys.
