Looking for good 20mm rear spacers with bolts - Any recommended brand?

H&R is a very solid brand that is usually stocked at a lot of places, or can be dropped shipped pretty quickly too.

unsprung weight's abt 10x , a 10lb spacer could mean 100 lbs ... reason I've never added them, on a separate note apexraceparts makes the lightest ones I heard

A 20mm aluminum spacer weighs...what? a few ounces?

Compared to the ~75 pounds each rear wheel and tire weighs, depending, it's pretty negligible.

lolz

its not unsprung if it's bolted to the hub. Its a total non issue.

Agreed. It's a non-issue.

Bolt 10lbs to the edge of the rim, or run a heavier tire, then that's a problem for acceleration...

Granted 10lbs does affect suspension responsiveness, but it's minuscule in the current state.

They only weigh ounces, not pounds. Running forged wheels with non run flat tires shaves off approximately 30 lbs a CORNER! now THAT is un-spung weight!

Just by switching from BStone RFTs to Conti DWS, I think it's almost 15 pounds per side in the rear. Unreal.
