Track wheel widths

[smudge 1020]

I need new track wheels and have been looking around at what width I want on the front

9.5J on the rear seems suitable for the Sprintex power I'm putting through them

But what's the realistic difference between having 8.5J on the front vs 9.5J?

I've got 9.5J all round with my Rays and I love the hold you can get on the road, bit I've never had them on the track. My old Work track where 8J all round and I felt like I needed wider wheels to put the power down

Anyone had experience of running 8.5J fronts vs 9.5J fronts?

I think you're liable to get more understeer, but obviously this could be tweaked out. Having 9.5J on the rear is no bad thing. I'm on 9J square atm and seems fine imo. There are times on track where I feel I need more grip but the reality is i probably just need to learn to drive..

9.5 all round, many prefer a squre set up. Too much grip is just enough !

Would an 8.5J front and 9.5J rear be better than 9.5 all round?

I wrote a massive essay in response to this but it is useless because:

 

This is another one that comes down to personal preference mate, you set it up how you want it, not taking others advice

But I haven't tried them both lol

Square set up is easier as you can rotate tyres.

Tyre width on a given wheel width plays a bigger difference given the same tyre - slight 'stretch' is better than a tyre too wide for the rim. e.g. 235 will feel better than a 255 on a 9" rim on certain tyres.
