Wheel specification

[Bhavd85]

Hi all

I am fortunate enough to own 2 sets of BBS RS2’s (700/701) which I plan on building Up to be 19’s

I wanted to get my head around the best specs to run for a 46.

I am thinking to take 4 fronts (rs700) which are 8.5J et22 and build 2 as 9.5J for the fronts and 2 at 10.5J for the rears.

Would that work? Is 9.5J too aggressive up front?

Feedback welcome

They do look good.
For the front, 9.5" et 22 has quite a bit of poke.
If the neg camber is increased to 2.5 deg neg, it will mask the wheel poke.
et 35 would pull it in closer to the strut, and at the same time give you the option of using spacers.
Care will be needed with tyre width as well, especially with the 19".
Are you using KW coilovers?
I run 9.5 et 22 18's and the poke is a little silly.

9.5 et22 on the front is pretty aggressive. I also run it, -3deg camber is required probably. For a road car it's a bit silly. Looks cool but a lower offset is probably more practical as long as you clear the strut.

What size tyres you planning to fit on the fronts? If your car is lowered, I believe the widest you can go on 19s is 245 and on 9.5J they will stretched inwards, couldn’t see the point. For fronts, 245 tyres fit perfectly straight on 8.5J, for the rears 275 on 9.5J, you probably don’t need wider tyres than this sizes, hence the need of wider wheels. I running 275 and 235 only because my fronts are 8J.
Regards.

I am happy to run some negative camber to a degree
I assume that means I’ll need new top mounts and yes the plan was to run kw v2’s or v3’s

Do you have a picture of the poke…the setup I was thinking would be 10mm more poke so I need to get an idea of how bad it would be

Appreciate the response

Only way to do that would be to shave the back pad on the rs2’s I’ll check if that can be done safely, if not I’ll have to drop the size of the fronts

Honestly not thought about tyres yet, I was thinking to run csl spec tyres as I have a set in the garage but happy to grab tyres as needed to get the right fitment and no rubbing. Thanks for the feedback though I’ll take that into account ✌
