Is this both front and rear? If you run a 7" spring in the rear you should be ok as the spring sits above the tire. In the front you'll have to run a different offset wheel I assume, I am sort of in the middle of experimentation myself...

The rear is fine actually forgot that detail.

Its just the front that is having the clearance issue. How did you fit the 285's on the red mr2 with these?! Thats what i wonder haha

PS Did you get the gland nuts i sent?

Ahh, ok... well, my front strut is drastically inclined "in" at the top with the custom special super duper prototype camber plates allowing me to tilt the wheels a lot less and still have plenty of negative camber... what size wheels do you have and what offset again? Also, I still have to use 10 or 15mm spacers up from to make them fit with about 3 degrees of camber. Now that the front suspension is all together I'll have a much better idea of how things fit....I'll have some updates in a bit...

PS: Yes I received the gland nuts Friday, thanks!!!

I mean your DD. Doesnt it have the coilovers up front with the regular camber plates? It fit your 285 wheel without hitting the springs.

No no no, I would never be able to fit 285's on the DD.... I ran 15x7 wheels with 205 8 year old worn out and flat-spotted hankooks at the autocross yesterday...

I was there we mounted it onto the car and it cleared the spring. It didnt clear the car when you turned the wheel but it cleared the spring. It was probly the offset on the rim allowing that.

Next thing, In ssm
"Any minor modification, intended to allow or facilitate any allowed modification, is permitted as long as it does not provide any intrinsic performance benefit in and of itself, does not provide a weight reduction of more than 1 lb, and is not explicitly prohibited elsewhere within these rules.This rule is intended to allow minor notching, bending, clearancing, grinding; the drilling of holes; affixing, relocating, or strengthening of brackets; removal of small parts, and similar operations performed in order to facilitate the installation of allowed parts or modifications.Minor strengthening, without relocation, of original chassis/suspension pickup points is allowed. Examples include welding washers restricting control arm mounting bolt movement, local reinforcement of control arm chassis mounts, etc."

Well i am looking at my camber plates and they will not allow for anymore camber beyond the opening.

I believe this rule states i can't touch that hole to allow for more camber.
I drew up what i am talking about in paint since i didnt take a picture of it over the weekend.

What are thoughts?

Ok, quick update from yesterday's autocross. The plan was to test the front suspension from the SSM on our DD to see if everything holds together, especially the RC adjusters. On Saturday I really quickly finished up the front suspension, it was a real hack job with no proper length hardware for the RC adjusters, the control arms were unfinished with weld slag still on the inside of the tension rod brackets (brackets not boxed in either), stock front upper mounts, basically eye-balling the alignment, 8-year old worn out hankooks (ventus , not even sure what exactly they are, got them for free from a guy heh), only about 1 degree of neg. camber all around etc etc... also, the rear suspension was stock original susp. with stock shocks...
Anyway, everything held together 100%, we did not have any issues all day. The car ended up with 3rd fastest time of the day (cars) and both Tara and I had a great time, the car was simply amazing fun-wise.

Here is a video of the front left susp, wish the camera was pointed more upwards...

You are correct Tim, remember though, that was with only 1 degree camber, 12 or so mm spacer and with the tire still touching the spring. So you'd have to have a very thick spacer or very low offset wheels to make it work. With a 18x9.5 wheel the offset would have to be about +10mm or even less to make it work with any decent neg. camber....

To gain more strut incline, you'll have to do a special camber plate that puts the shock top (adjuster knob) under and inside of the strut tower like I showed you on my setup. Randy Noll did his own camber plate too which was a great idea.

yea i agree i dont think i can touch the opening as well.

Though that rule does state that you can drill the holes to allow the modification so why wouldnt you be able to use the 10mm's?

I have always assumed that you COULD drill or cut new holes to access your adjuster if you wanted.

The rules say "suspension is free", meaning you can do absolutly anything you want to it so long as it mounts to the stock locations. From there you have a "minor mod" (drill a hole) to facilitate an "allowed mod" (doing whatever you want to the suspension).

I don't know, its a bit of a gray area I suppose, but the way I read it it should be allowed.

That's the way I look at it also but just wanted to make sure that the car is 100% legal without any issues whatsoever. I have just always been careful with the "can't touch the pickup points" phrase... thank you (both Tim and Alex)

The problem is its a mod which you can't undo easily if it isnt allowed.

Modifying that hole is strictly prohibited in SP, however, I think this is exactly what the "minor mod" exception was intended to permit but then I have been out of the SM loop for a couple of years now.

I made a thread on the SCCA forums in the SM section seeing what other people think about the ruling on opening up the strut tower holes.

I read it as a legal minor modification, but always ask for clarity from your governing body before actually cutting.

Unrelated question... what kind of wear do you guys get with A6's or similar? More rear tire wear or front? My alltrac used to wear the fronts a LOT quicker than the rears and at our last event the rears on the MR2 didn't seem to wear that much at all...hope that's a lasting trend. heh

Im about to modify my struts to accept the Koni inserts and was wondering if anyone has tried a shorter spring in the front. Will the geometry still keep the collar below the tire and rubbing? I guess i may be stuck with 225 but i wanted to weigh my options first. I do have some 6" springs im going to try first but im concerned with travel vs. binding on them. I notice you guys are running 8" and 7" springs. Any thoughts are welcome
