new setup:

everything new up front from M+ grab a track
shelby drop
620 coils half coil cut
245/45/17 tires

it rubs the fender lips..

so... i've seen ppl cut half coil and be fine, just wondering if its my 245 tires up front? i had 225s before and it was fine.

option a: air shocks to make me go up like 1/2 inch
option b: coil spacers
option c: roll fender lips and HOPE that fixes it
option d: new 620 springs which i dont really wanna do.

 

225 are about as big as you can go on the front.
I would roll the fender lip and see if that gets rid of the problem
I fit does not fix the rub, buy 225 to replace the 245 up front and run a staggered set up. Keep the old 245 for replacing the rear tires.

I have 225 50vr tires on 16x8 with 3.5 backspace with no problems. (620 springs up front)

 

im runnin factory 03/04 mach wheels 17x 8? so i gotta stay 17 inch tire. maybe a 225/?/17

 

It really depends on your backspacing of the rims.
Check your back spacing and tire size here:

Dodgestang made a nice database of what works for wheel combinations.

Another option is to install a Vario-Centric Camber Kit. This will eliminate the shims on the upper control arm and put the adjustment on the lower control arm. This will usually pull the top of the tire inwards by a 1/2 inch because the UCA is up against the tower.

While your at it do the Shelby drop.

And then to finish you should uses adjustable strut rods, This will totally eliminate all of the shims for caster also.

You will be able to get perfect front end alignments with this and pull your tires inside the fenders by 1/2 inch.

Just some more options that could solve your problem

Good Luck

Adjustable strut rods require later model LCA's. The bushings on 65-66 LCA's aren't designed to accommodate adjustable strut rods.

I'd roll the fender lips before anything else. It's free. If not, then you may need to drop down to 225's.

A third option is to reduce the size of the wheel spacers/adapters by a hair. You should be able to do this with 17" wheels.

 

Rosehill makes adjustable strut rods with sealed hiem joints to eliminate the bushings all together. Daze also has a nice write up for making them yourself.

I agree rolling the fender is the best and easiest option. Harbor Freight now carries a fender roller for 80 dollars that is almost exactly the same as the one Eastwood sells for $240

what tire size should i look for then? 225/?/17?

 

I don't think you can get the fender roller from harbor freight anymore. I looked and couldn't find it and all the links I tried lead to a page that said it was discontinued or no longer available.

 

Man you are right! My bookmark is no longer good. I was going to pick up one to do my fenders before I cut 1/3 of a coil just to be safe.
I called my local HF and they checked and it is back ordered and they said it should be back in stock this October (2009).
I also noticed Eastwood reduced the price of theirs. Maybe they saw they were not the only ones selling them now...

 

did some homework.
current tire size 245/45/17 are 25.7 tall by 9.6 wide
225/45/17 are 25 tall 8.9 wide.

i would lose .7 (roughly 3/4 inch) in the width but also loose the height by the same. not quite sure how the height difference is going to help/hurt me.
