Yeh, this billydeakins - who is that guy?

Great taste in wheels. Both sets look look really good...

Wheels are nice looking but definitely on the heavy side. Here's my car with them on though:

Bump from the graveyard... just wanted to thank you as i ordered these wheels last night, based on your pictures. my car will look very similar to this for the 2021 season.

Went with 17x8 et30 and 17x9.5 et20 directly from MOMO. Now I have to find some rubber to wrap them with, and based on this thread, 215/45/17 and 245/40/17 looks like the way to go.

X JBM X, how did this end up working out for you? Thanks,

Lots of good info here, especially the spreadsheet excerpt. I made up something similar to determine the parameters for 17's on my '87 3.2.

I'm currently running 7.5 x 17 ET23 on the front and 9 x 17 ET15 on the rear. The very well-used Michelin Pilot Sport 225/46-17's I got with the front wheels were just too wide unless I wanted to raise the ride height excessively and/or run way too much camber.

My current tyres are Firestone Firehawk Indy 500 (which I like a lot) in sizes 215/45R17 and 255/40R17. Despite going down from 225 to 215 on the front, I did find that the ET23 offset made it advisable to partially roll the front wing (sorry - fender) flanges to avoid upper sidewall damage.

Just bought the MOMO heritage 6's , 17x8 front, 17x9.5 back. Trying to figure out what size tire to use with the least work on the car (1985Carrera 3.2 coupe).
Wondering how yours turned out X JBM X
Need to buy tires now.

You've got 2 obvious choices and one or two fringe options as well mostly track oriented though
215/45 & 245/40 or 225/45 & 255/40 are the main choices
use the smaller for a livelier car and the bigger for more grip
