Ispiri FFR6 - Carbon Graphite - Will they fit?

[mr wilks]

For Si Z4 as a rule of thumb aim for front 8.5j et 38/42
Rear 9.5j et 35/42
From those numbers a little variation can work but you would need to pay attention to tyre sizes

In particular, I had been eyeing up some out of stock CSL reps that I thought were a good fit (Front 19×8.5 ET38 & Rear 19×9.5 ET43), and they've just come back into stock on the same day I read this! Coincidence? I think not....

But before I do unspeakable things to my credit card, I've 2 questions if you would entertain them?

- What would you suggest for tyre sizes? (a range for profile/width that I should aim to stay within would be a great help).

-

Those wheel would sit & fit a treat , tyre sizes for me would be 235 35 19 & 255 35 19 though possibly 225 35 19 front if the car is sitting low
