2 deg camber all around

running a narrower tire but as out as possible could well be equivalent in perf & handling to a wider tire , in another words using a 255 but space it as outside as possible,( and spinning less weight ....)

Your thoughts ...!?

Right spoke with GTOne who currently have my wheels.

Front, we're going 3m shims (= ET52) with -2 degrees camber.
Rear, we're going to try 15mm adapter (= ET40) and 11mm (=ET44) shim with longer studs and deeper nuts as plan B with - 2.5 degrees camber.

Can't wait to see it all done. The rear camber/ offset should perform and look awesome.

Interesting,

Mr. Alex is running ET40 with -2.5 camber and experienced rubbing - I'm assuming this pic shows the car at a higher ride height and no rubbing?
Sean is running ET37 with -2.5 camber and has no rubbing.

I assume the discrepancy is due to an initial very low ride height on Mr. Alex's car...

A more powerful engine will demand more from the tyre/road interface when transmitting a higher torque, so don't go mad with the rear camber Frank. More camber = smaller contact patch = less tractive grip; you might go around corners better but will not be able to get the power down on corner exit with the inside tyre running on its edge.

This...in the sense that camber is a tuning tool individual to the needs of the driver (in this sense, not meant to fit wheels and tires).

It is best established trackside with a pyrometer, not as a function of what looks best.

Same page - we'll see. Cheers,

That car is going to be fabulous. IMO, silver or black for the inside of the BBS wheels. Never been a fan of gold.

you need tyre width also to add to the comparison .. and ride heights as you sugguested.

this was my summary .. but ended up with a bit too much clearance .. maybe 5mm or so too much.

Wheel =10ET40
Height = 228mm rear (RS+5mm)
Camber = -2 degrees (max with stock suspension)
Springs = 650lbs
Tyre = 265/35
Fender Lip rolling = 3mm
Fender Flare rolling = 4mm

Mr.Alex

My arch is not rolled though unlike Kiwi, if I did I would have a few more mm of clearance.

Here are the pics as requested Frank. Sorry they are just from iPhone. The lip was rolled and guards flared when I had the work done so I'd say 10J ET40 is probably best. It will give you flexibility between tires too, they all have such different shoulders and profiles between brands and types that you cut it too fine and you're limited in options. Options you'll need if you're going to be doing track days etc.

Actually I just ordered another set and left my rears as is with a 10J ET 43 for this very reason.

Porsche964FP

Ahhhhhhhhhh here's the key - the flare.

That's not possible on my car so fingers crossed ET 40 will squeeze in with the flattened arch lips. Otherwise I will go ET44.

Thanks Sean.

Mr.Alex

Rolled arches should fit it fine, but also depends on tire brand, size, and occasional design of wheel to see how much stretch the tire might have if you choose a narrow-we tire.

Got an email from Peter - he's got another customer who's having the same wheels and tyres fitted... lol

except it is still at SUV ride height.

Ahh, so that's what my car looks like with the new wheels - cheers Frank!
Still some work to do, some 7mm shims on the rear and then some adjustment to prevent oil pipe rubbing!
I don't have the centre caps on mine that you do though!
