Widest Tires up Front on Dinan Springs
Hey guys, just wondering if anyone has any knowledge about what the largest tire we could fit up front when lowered on dinan springs. I would like to be able to run a wider square setup than the 225s currently on the car.

I have 2.04 mm clearance to the shock tower and still rub on the fenders which have been rolled/mildly pulled. I'm running a 235/40 r18. Maybe you could get away with a 235/35 r18? Or 17 rims with a smaller rolling diameter than my rims. |

I have been running 245/40 Dunlop Direzza IIstars on 8x17 et 42 wheels, first on the stock suspension and now with Dinan springs, bump stops, sway bars, and camber plates. No rubbing on the street, autocrossing, or on track. Today I mounted up a set of Apex Arc8s 8.5x17 et40 in front with 245/40 Bridgestone RE71Rs on the front and 9x17 et42 with 255/40 RE71Rs on the rear. Took a 5 mile drive just to make sure everything was OK. No rubbing on the road but won’t get a chance to try them in an Autocross for a couple of weeks.

It depends, on many things...
The wheel, tire, suspension setup, camber, etc will all play into what will be a working option. On stock ride height with no spacers on a 7.5 or 8.0 wheel, you can get away with a 245.40.18 up front with mpss. Slight rubbing with 235.40.18 on nt01 at full turn. Rear also fit these sizes with no issues. With Dinan springs, camber at -2.0 all around, i have to go to a 35.18 sidewall rear or i rub with anything over a 225. Apex arc8 8.5/9.5 with 235.18.40 nt05s fit in the front, but rubbed horribly in the rear due to ride height. I also have a hard time finding a matching set of tires that are extreme summer or rcomps in a 225.40.18/245.35.18 config. Ill prob just stay with my re71s in a 225 square with spacers. Any thoughts?

BTW, OP and the post you quoted are about Dinan springs, not coilovers with camber mods. I only included my specs because it's similar. |

Ok so im about to go with Apex ec7's 18x9.5 for the rear.
I'm pretty sure i want to highest offset ET58 unless someone can tell me why to get another et? Im going to be running re71r's, whats the widest I can get away with on Dinan springs in the rear? I have 10/12/15mm spacers available. 255x35x18, or try to fit the 265 35 18?

so after reading thru all the comments, looks like i will just be going with 235 in the front and 255 in the rear w/ VMR V710s, camber plates unfortunately cost too much to justify going for a larger square setup :/

Installed the 245/40/17s on all 4 corners.
Car is lowered on Dinan springs. Front is a tight fit but I went on a long test run on windy/bumpy roads and so far no rubbing. Track day this Thursday will be the test. Here is my how stupid can you be moment today: I removed the stock wheels and spacers and installed the new wheels. Went to test drive the car and it wouldn't move! Realized that I had used the longer lug bolts that were necessary with my spacers and one of the bolts on each rear wheel bound on something and the wheels wouldn't roll. Don't want to look to see what I fu*ked up. |
