Going back to the Alfa briefly, if you already have 15mm spacers, your wheels are 19x8 or whatever ET26 already. And you are still tucking, so increase width a little and you'd be sitting flush, or just push the offset if you aren't going wider than 8s.
Well if you have pushed the wheel out 21mm over the standard, (ET41 to ET20), you've increased your inner clearance by 21mm also, then increasing the overall width of the wheel by 0.5", is roughly 6mm poke either side, so in the end it would be ~15mm MORE inner clearance, and ~27mm MORE poke.
*This is over the standard wheel, over yours currently with the 15mm spacers its more like exactly the same inner clearance, and 12mm more poke. Which after re-reading my entire post, makes that ET0 very ambitious.*
I think that's right, total increase of ~15mm over the width of the wheel (8 to 8.5). Got to also take into account you are planning on slimmer tyres too, so the clearance needed by those will be less.
Looking at Breras on Google, particularly this one,
Dial in a degree or two of camber to match the arch work lines, and you could easily push them 30mm from standard offsets (ET10 on 8J), which is only ~5mm more than 8.5 on ET20. The lower you go, the more space it will create.
I think if you are going to do this, you need to really get adventurous. Don't listen to the advice of any Alfa owner. I'd consider looking as close to ET0 as you can get, on a slightly smaller wheel like 18s/19s not 20s. Take one of your spacers off and stick it on same side so you have two, and push the wheel on and see if you can hold it on and let it down from jack and look at your clearance.
thanks for all that.
I will have a go at that, so having two spacers on one side would give me an idea of et11?
This is what it looked like bfore lowering and spacing, if that helps.
It always sounds so much more complicated than it is. Whenever I try to explain to anyone they just look at me confused. Just get some of us to take a look at the meet if you come in it, or grab some pictures looking along the side of the car, and from above the wheel arch, and of the gap from tyre to arch, ideally with some kind of measurements.
I dont trust ME with it either, it'll be like the car park guys, in 'ferris buellers day off'
I just realised how high breras are..... bearing in mind that is the brera S, which has the Prodrive suspension on it, which is somewhat lower than a standard brera.
Find out if you can disconnect the ODO without anything like a tamper dot or if its stored on the cars ECU rather than dials. If theres a will theres a way.
