Then you're probably good. A lot of folks, especially at the regional level, miss this one.

The fronts are MacPherson Struts.

http://en.wikipedia.org/wiki/McPherson_strut

When top mounting point moves around, it moves the orientation of the wheel with it. Strut bars and other such braces, serve to keep the geometry of the suspension close to what you set it at.

Rears are multilink:

The orientation of the coil and shock don't affect alignment of the wheel.

I would post a picture along with the mounting points. I really don't think it is legal, but I may not be interpreting the rules correctly.

cheers

i guess i am just using the wrong nomenclature. i've always seen it refered to as a "rear strut tower brace". i never even thought about there being no struts in the rear. haha.

the 4 pnt brace would attatch in place of these two individual braces:

and the brace would look similar to this:

 

The H-Brace that you have pictured is not legal.


I do have a question for those of you in the know though. Turbo manifolds? Who uses them? What brand? The two Borla's I have ordered (6 months ago) are STILL not here. I'm in a state of panic at this point. If you have a vendor you like or reccommend I'll buy them there. Tired of waiting on mine from my vendor.

 

From what I'm told, and you can take this for what it's worth, the best bang for the buck is to port the stock manifold and O2 housing. I have yet to do it because that's down on the list of priorities but unless you're going to a full race header, that would be the next best thing.

 

I've got the ebay o2 housing on there already. My concern is not nessecairly power gains but weight. Owning the MR means we have the heaviest car in the group. Tubular Manifold should drop some weight off the front of the car.

 

I would probably look at the Invidia or DC Sports header then. I'd try and stay away from the 304 stainless steel headers.

 

Thanks Russ

 

Well it's not just that. Since they're not struts, a bar attached to the mounting points doesn't really do much of anything...make sense?

yeah, makes sense.

 

Mr Dieman,

Full-Race! You must have seen mine at Nat's, right?

I have no idea who your vendor is, but it's not their fault on the Borla header...it's Borlas. We've been waiting longer than six months for them.

You'll probably wait a while on the DC Sports, though if you find one in stock it's the old style, as the new version--that has been in a redesign state for at least six months--is due out any month now and is supposed to have slightly thicker walled tubes to help prevent cracking.

The Invida can be gotten, though my notes say it "requires an aftermarket radiator" (if anyone can prove/dis-prove that please let me know).

There's also the GT Spec header, though it is stainless steel also.

 

The Full-Race manifold is a quality piece. But if you're looking to save weight you'll be disappointed, it's the same weight as the stock manifold+heatshield. They both weighed 13.4lbs on my scale.

 

Yes I did and I liked it alot. I know you do too. I was definatly looking at that. You have anyone I should/could talk to about it?

JSC, Ya I'm not blaming my vendor(I probbaly didn't word that right). I know it's Borla's fault, that's just all they carry though.

spaf, thanks for the info. I didn't know that about the weight. I obvisouly hadn't pulled mine off yet.

 

Meet with my tuner again tonight and we logged a run in 3rd gear that shows the boost/AF and took a screen shot of it. I'm sure someone will try and find a way to poke holes in this but the data shows the maximum boost I'm running is the stock 18.8which then tapers down to 15.4 or so at redline. No boost creep what so ever. The graph you see is from a bogging 2k rpm up to my 8k redline.

 

Obviously I have too much time on my hands and I am trying to mess with tire size.

Tire Rack has 245/45/17 RE01 on sale for $148, which is $17 cheaper than 245/40/17s and Bridgestone $100 rebates ends this month. Other than money and top speed which 45 has advantage of 40s, does anybody use 45's and lower the front end more to get better corner weighing? Since lower the front end too much impacting steering, I am wondering if anyone here use the tire size to increase the ride height and lower the front end to achieve better weight balance without hurting steering. Or am I just stupid by asking this question. Thanks.
