Need your Opinion Please :)

So I really don't like how my rear wheels are not flush with my fender and its kindov hiding inside my fenders... what size spacers do you guys recommend I purchase?

I have iForged Drift 19x10 and 19x8 with I believe 28 offset in the front (front is fine... fairly flush with the fender) and 38 offset in the rear (rear is what I need spacers for). I didn't pick my offsets and wish I had told iForged which offsets I wanted... too late now though so please take a look at the pics and let me know

Thanks,
PJ

**EDIT** Oh and I would like some minimal rubbing as well (because I know either way I'll have rubbing)... I am sitting on H&R Sport Springs + Koni Yellows. Thanks again!

Here are some pictures for your reference:

maybe a 5mm spacer? see how you like that, and if you dont you could MAYBE try a 10 but you'll most likely rub...

5mm only 10 will rub...even with 5mm the fenders might have to be rolled for no rubbing issues at all!

Loooks great as is but may look better with a 5mm spacer. I have the same dilemma, as my rear offsets are too large. I think I can fit a 10mm spacer as I have more room with a sedan, and I'm going to give it a try.

dawgdog let me know how it goes with the 10s... I think 5mm will be too little and 10mm will be perfect but I'll rub.

Anyone have pics? past experiences?

Thanks,
PJ

Do 10 and then find a good shop that can roll your rear fenders.

Looks good as is. Maybe 5mm, but you should try and avoid spacers.

Quoted from carbibles.com:
Simply put, sprung weight is everything from the springs up, and unsprung weight is everything from the springs down. Wheels, brakes, shock absorbers, springs, knuckle joints and tyres contribute to the unsprung weight. The car, engine, fluids, you, your passenger, the kids, the bags of candy and the portable Playstation all contribute to the sprung weight. Reducing unsprung weight is the key to increasing performance of the car. If you can make the wheels, tyres and swingarms lighter, then the suspension will spend more time compensating for bumps in the road, and less time compensating for the mass of the wheels etc.
The greater the unsprung weight, the greater the inertia of the suspension, which will be unable to respond as quickly to rapid changes in the road surface.
As an added benefit, putting lighter wheels on the car can increase your engine's apparent power. Why? Well the engine has to turn the gearbox and driveshafts, and at the end of that, the wheels and tyres. Heavier wheels and tyres require more torque to get turning, which saps engine power. Lighter wheels and tyres allow more of the engine's torque to go into getting you going than spinning the wheels. That's why sports cars have carbon fibre driveshafts and ultra light alloy wheels.
Spacers add to the unsprung weight. As they are small in diameter, their influence on inertia is negligible.

So now that U "know", it's on U to decide what do U prefer, to pose or to perform...

i have a 10 inch wheel with a 35 offset on my coupe and it sits pretty flush but i think a 5 mm spacer would look really nice on my car.
