Default DMS 50's & tire clearance

I ran into a problem using the DMS 50's with 215/45-16 tires on stock rims. Not enough room between the back of the tire and the coil overs. I'm also concerned about potential clearance problems with speedline 2118's. Has anyone else encountered this? The only recourse I can think of is to use wheel spacers, either 5 or 10 mm with appropriatly lengthened studs?

Has anyone else encountered this? Can anyone recommend a wheel spacer manufacturer?

The biggest bummer is that this is keeping me off the track tomorrow (unless I want to run with the snow tires )

Thanks,
Steveson

It's Blue, ok?

what kind of DMS 50's? Street length, rally length?

Are the tires rubbing on the spring perch or the spring itself? I have heard that H&R makes a spacer, you may need a 3mm or 5mm spacer at a minimum. Problem is anymore than that could cause problems with the lug nuts and stud length.

Another thing to check is the washers used in the rear. Make sure you have the black ones installed to max positive camber.

I haven't had my 2118s and DMS 50s on at the same time yet, but I doubt I will see any interference issue (with 205/65R-15 tires). Many rally guys use this combination of suspension and wheels/tire size. It will depend on what size of tires you have.

Also, there were no problems with the DMS 50s and stock wheels with 205/55R-16 tires. I had my camber at -2.5 deg in the front and -1.5 deg in the rear. There was little under 10mm of gap between the tire sidewall and the spring perch.

The tires contact at the spring perch/adjusters. I really dont want to use the spacers. And I now know that I do not have the black offset washers in the car, they're sitting right in front of me... I'll switch them out today and see if that cures the problem. Thanks for the info.

This problem occurs with the wagon having a shorter width in in wheel base versus the sedan. I had problems with the clearance as well with my sedan, but that was with 18 x 7.5"/22540R18 shoes on.

The black washers will give you an insane amount of positive camber, this is only a temporary fix. I would get spacer to allow you to set your alignment with what spec's you want.

actually the problem would be with the track of the car, not the wheel base. ;p

clearance problems in the rear I would expect to be between the tire and fender if your using the black washers.

FWIW, the black washers set at max positive camber are only giving me the stock -1.5 degrees camber. I run DMS 50 street length struts using GC8 STI top hats with DMS adapters.

Ok, resolution here.

The 215/45-16 Falkin Azenis DO fit on a wagon with DMS 50's (rally gravel length and valving with GC8 Sti top mounts and DMS adapter plates, gold camber washers)

Just barely, just...

About three business cards thickness seperates the side wall from the spring perch.

Now I was really afraid of fragging my new tires. I was certain I'd gouge the side walls, but flogging on my personal rally stage (my 3 mile driveway) and yesterdays auto-x confirm that you can get away with it. Sorry about the confusion and all. When I first mounted them I didnt put the car on the ground and roll it around. I eyeballed the clearance and from what I saw it was a no-go.

So yes, it can be done without spacers or crazy rear camber adjustments.

Next, will they work like this with speedline 2118's (15 x 7) ? When I get my Khumo's I'll report back.

BTW Azenis are a great tire, best bang for the buck.

BTW snagged 4th novice out of 14 with the rex, posted better times than any of the corvettes and S2000! I'm very happy with the car and everything.

Default re:

Check what washers you are using as well as your ride height.
We have had no trouble with wheels and tires rubbing on ANY 50mm when they are installed right. Normally the black washers should give enought clearence without offsetting your allignement too much.

If not, use a scrap rotor, machine off the rotor and keep the seat or hat. Studs are no trouble, we have a metric supplier for longer ones.

Regards,
Mark

I've used Speedline 2118s with both Pirelli gravel tires and Nokian snow tires without any trouble. That's with 205 gravel tires and 205 snow tires. Keep in mind there is very little clearance between the lower spring perch and the tire, but very little is enough. My 225/45/17 S-03s on +48 Rota Attacks work without spacers as well, just barely. Now my 245/45/16 V700s on 16x8 Gram Lights, that's another story...

Yep, ditto here.

No problems with DMS50mm gravel and falken Azenis. No other mods.
