Ok, so I did search on here, got some input....but I'd like to know some more before buying today or tomorrow.....I am lowered on the Eibach pro kit. Have the coupe sport 19inch wheels with OEM tire size. I want it to be as flush and as aggressive as possible with no major rubbing. What is the best best. 20mm front- 25mm rear? Or 25mm front and 30mm rear? Thanks in advance.

Much will depend on personal taste... Alot of people do 20mm which puts the wheels/tires pretty flush on an oem setup with 19s

You'll be the first to run spacers on a coupe, great day for science

I think I'm going with 25mm front/30mm rear.....think it'll rub bad? appearance?

Those are some aggressive spacer sizes...my research showed most did 15mm front and 20mm rear. I went with 15mm all the way around simply due to the negatives associated with them...keep in mind the thicker the spacer the worst the effect of these known problems (below).

-Changes scrub radius which can increase tire wear, changes dynamic toe characteristics when braking and accelerating, and your stability under braking.
-Changes effective spring rate due to the wheel being further out and the leverage it has on the spring.
-Reduces wheel bearing life due to higher load on it because of wheel further out.

I would HIGHLY recommend doing 20mm all around. 25mm and 30mm just sounds way to aggressive for stock wheels. And I'm pretty sure you'll have to trim/remove your rear bracket.

Use my thread to help you get a better idea and picture of what 15mm looks like. 30mm you'll be sticking so far out it'll look like a hot wheel car.

20mm/25mm it is than.

Yea, spacers and springs are the top mod on this forum. I am guilty of doing them too.....

so guys, sorry to Hijack the thread but regarding the installing of the spacers:

Did you guys use Loctite on the threads, and anti seize behind the spacers?

NO loctite! Proper torque and check every wheel rotation at minimum. Anti seize is fine and recommended if you're in a ****ty climate. I have 20mm all around and there's just no way I'd go any wider. It's flush without looking stupid.

I used anti seize behind the spacer so it wouldn't be stuck as well as the bolts. I had 15mm all around on stock sport suspension and it was an awesome awesome look.

I am about to put some spacers on and I have been reading everywhere even on Jeep forums the following:

- Cleaning the original surface then a bit of antizeize on the rear of spacer.

- Blue loctite (no red loctite) on the original studs ( which the spacers attach to) and put nothing on the spacer studs which the wheel now attaches to.
Note: This may be overkill but blue loctite is not "permanent" and is "designed for the locking and sealing of threaded fasteners which require normal disassembly with standard hand tools." So this added amount of security seems harmless.

If this is incorrect then please alert why ...

Agreed ^ I put 15mm on mine today on the rear and looks just about flush anything more would look silly maybe 20 on the rear at most like Kenny recommended.

Show some pictures of yours so he has an idea of how it'll turn out... I bet it looks perfect!

Went with 20 mm in front and 25 mm in rear. Perfect stance. Sit's almost flush with the fender and drove it aggressively around turns and such no rubbing at all. Perfect size IMO if you have Eibach Pro Kit springs with the Coupe S wheels.
