Crap... I didn't do that... and it's been snow and rain ever since I put em on


I would give the rs3's a slight advantage over the NT05 for colder weather traction and cost

Wow! Is traction better in warm dry too?

Yea, 2 unlike metals cause accelerated corrosion.

I'm about to order some light custom wheels so that I can get more rubber contact and less unsprung weight.

How much clearance is between the stock 7.5x18 et45 wheel and the front strut? I'm hoping for a setup like this:

Front: 8.5x19 et44, 235/35 MPSS tires, that makes 11.7mm closer on strut side and 13.7mm more poke than stock on the fender side.

Or et43 in the front would give 10.7mm closer to the front strut and an additional 14.7mm poke towards the front fender. I was trying to keep the poke down to a minimum.
http://www.willtheyfit.com/index.php...culate#content

Rear: 9x19 et53, 265/30 MPSS tires, that makes 13.7mm closer on the strut side and 11.7mm more poke than stock on the fender side.
http://www.willtheyfit.com/index.php...culate#content

If this looks OK, what will happen if I install the M3 LCA? Will that give it less strut and wheel well clearance?
The wheels are expensive, I don't want to screw it up.

There is very little front strut clearance up front in stock form. I got a rough measurement of about 15mm


My math is saying your wheel will be 12mm closer to the strut, while the tire will be 4mm closer.

While the tire will be ~6mm further out towards the fender and the wheel 14mm closer to fender.

I think with a very small spacer you would be just fine.

But I am no expert! go measure for yourself and be sure

Thanks. Well since they are custom wheels, I can make them any offset I want. I'm trying to avoid spacers.

Does it make sense?

I also agree with you! I was just saying I've got closer clearance and haven't rubbed yet.

However if you were taking corner the opposite direction the tire may not be deflecting, but technicality the force will create a moment about the hub which would want to rotate the whole wheel closer to the shock.

I would assume that the wheel is strong and stiff enough where this deflection is virtually 0 though
If you take the corner on the opposite direction most of the weight should be on the opposite wheel so if there is no rubbing on the wheel with the weight there will be no rubbing on that one either

I was scared a bit first but then I took the wheels of and the struts were intact. I also have about 3mm clearance with the kosei 17-8 et42 with 245s all around

Are you sure that wasn't feedback for the RE71R? I run RE11's and with them being really popular with the Nissan Z community (used to own a Z) I can say the wear is totally normal for the category, and wet performance is good.

Ah shit. You're right RE-71R. Sorry man. All these tires are making my head spin.

Plus, I've been going back and forth on my big turbo build with the vendor and shop. Ugh.

Hehe, it's more because of the eLSD not being able to put power down... I think.

Which bushings did you change to? How involved was the install?
