Thinking about Rotas - Offset Suggestion?

[Kevin 1G Drummer]

I ran a 235/45/17 on a 17x8 +35mm on my DSM and I thought it looked really good. the rears were tucked in just a little, and the fronts stuck out about a half inch. With about a 5mm spacer the rears would have sat flush. No need to clearance the rear control arm either. My winter wheels are 1st gen 3/s VR4 wheels, and with those I needed to grind a little bit off the flange of the rear control arm since they're +40mm offset. Same size tires as the summers, and the fronts sat flush with the top edge of the fender.
