Safe ET?

I've been looking for wheels for ages and the guy sorting our car out is an engineer and he reckons we should stick to OEM ETs for the wheels otherwise there will be strain on the suspension. Is this true? Is there a range where consquences will be minimum (i.e a lower ET so the wheels can come out and line up with the fenders/arches better!)?

Cheers,

To fit perfectly the fender some calculations are needed. Maybe your engineer is right but the consequences will be negligable. Depending on your wheel size ET differs. Front with 8' and ET 40 and rear with 9.5 and ET 40 looks perfect.
 
Rob,

Flush with the fenders does not always == less stress on the suspension.

NSX-Racer from Germany has been using spacers on his stock wheels and slicks, and so far he seems to be doing ok. (Slicks will be able to pull more lateral g's which should result on more stress)

There are many other folks who are running with slicks and aftermarket wheels with various offsets and they seem to be doing ok as well. Just be diligent with the car inspection before and after track events.

The offset (ET) that results on a flush look will vary between NSX's with stock brakes vs BBK's because the rotors on BBK's tend to be thicker.

Good luck!

Sorry to resurrect this but how do you calculate the ET for the wheel size? The wheel size we are getting is Front: 7.5' and Back: 9'

Cheers!
