Not quite related to the XXR 527 thread yet but it'll be relevant for someone who may be looking to have the same setup as mine.

Photos are of the clearance between Michelin PSS 225/45/17 on the stock 17x7 +48 wheels.

I have RCE Yellows, 14mm OEM crash bolt on the top, SPC adjustable camber bolt at the bottom.

I have the following alignment specs:

Front Driver Side: -1.6 camber
Front Passenger side: -1.6 camber
0 total toe up front

Rear Driver side: -1.4 camber
Rear Passenger side: -1.3 camber
1/16" total toe

I don't race around on the track though I do take on corners on the aggressive side when there's no cops/traffic. I do a lot of highway driving. On a rare occasion, I'll go on drives around the mountains/twisties.

As can be seen, clearance for the said camber/tire/suspension setting is on the closer side of things. I used a paint brush to check for clearance. The driver side clears it just fine. The passenger side, I have to finesse the paint brush handle to go through with little to no resistance. This is of course going by feel.

Digital caliper says that the said paint brush handle was about 7.75mm thick.

Found a wheel/offset clearance calculator which I just accidentally closed. Yes, I have to find it.

According to it, when moving from a 17x7 +48 wheel to a 17x8.25 +35 wheel, the rim will stick in about 3mm towards the car...the rest of the width sticks out away from the car.

Going with this, I may lose another 3mm of clearance...leaving me with 4.7mm (.185"). That's a bit close for comfort to me as I'm not very experienced with settings and what not.

I've read that 3-5mm spacers would be the widest thickness that we can use to increase clearance without using extended studs. Adding another 3mm to the 4.7mm clearance will put me at about .3"/7.7mm...

Thoughts?

Edit: If anything, it looks like it'll be the tire's side wall and the surface of the spring that are closest to each other. Will it rub at 4.7mm/ 7.7mm when cornering hard? I'm on Michelin Pilot Super Sports if that matters.

--------

2nd edit: supposedly there's going to be a 17x7.5" +40 XXR 527 coming out. Per a rim calculator, you gain 2mm of clearance with these over the 17x8.25 version. That wheel would be just about perfect with the 225/45/17 tire with a bit more camber for those looking for much better grip than stock.

I should be getting my 17x8.25 +35 XXR 527's tomorrow along with hubcentric rings and muteki sr48 lug nuts. I should also be getting my 3mm hubcentric spacers as well.

I may be getting everything done by Friday (12/4) afternoon.

On a side note, it's been 26 days after a Jackson Racing Supercharger has been ordered from FT86speedfactory. Might be time to hit them up for an update on it =^_^=
