So my FD has a molded wide body kit on it 30mm over stock and I want to know what's the widest wheel set up possible. As of now I have 235's in the front and 265's in the rear. The guy I bought it off of said there's plenty of room to go wider. Any recommendations ?

 

make sure you don't have "stance" wheel offsets. With your tire size, it sounds like you do. With 30mm extra if you have a set of wheels with a proper offset, you could get 295 tires square.

 

Idk if this counts as stance . The front wheel aren't straight but it's not negative at all

 

you will need different offset wheels to run a wider tire

 

So If I wanted to run 18s with 295 squared setup what would be an ideal offset cause I know nothing about it.

 

18x10+50 should work

That offset works to fit 295 front/rear on stock fender FD.

Fitting wheels/tires aggressively on fiberglass wide fender cars is tricky. +30mm fenders rarely are and furthermore the lips cannot be rolled on fiberglass to get the tire closer to the edge.

Also, if tire contacts fiberglass wheel arch it often cracks the bodywork.


Best thing you can do is set your camber to what you want to run, confirm the width and offset of your wheels/tires and MEASURE how far it is to the fender lip in MMs and calculate what wheel/tire width and offset you can use.


We know FD can fit 7.75" in from wheel mounting surface (backspace).

We know wheels are 1" wider than their nominal width (18x11 is 12" wide edge to edge).

We know that running tire taller than ~25.3" tall in front will require you to modify the fender liners and unibody around the headlight area (do don't do it unless you have a real good reason).

This pretty much limits you to the same 295mm wide front tires you could fit with rolled stock fenders.

18x12 +25 to +30 with 295/30-18 is a good starting point up front.

Rear will fit that too or you can go with a taller/wider tire in the rear like 18x12 +25 to +30 with 305/30-18 or 315/30-18.

But the less offset you use (to maintain that 7.75" backspace) the less wide tire you can use by a factor of two (inside + outside).

So, if you could (and you probably can) fit a 18x12 +30 with 315/30-18 in the rear and did 18x13 +15 instead you could only fit a 285/30-18 on the 18x13 (big stretch).

So 18x12 +30 front and rear is probably the sweet spot, but measure!

 

Thanks for posting on this. I figured you would sooner or later.
