Im running the following setup

H&R sport springs
stock wheels and tires.

what size spacer are you guys running front and rear.

dude how are the tyres and spacers help in the cars

HUH?

guys with stock wheels are running 5-8mm in the rear and 10-13mm in the front.

If lowered I say go with a 5mm rear and 10 mm front spacer.

I'm running 10mm in the back with a drop (H&R 20mm springs).
I'm gonna go with 15mm spacers in the front

no rubbing? and are your springs the H&R sport springs? they lower .75 inches front and rear?

They are the 20mm springs so yes - 0.75 inch.
