20" wheels on a ECE 4/6 kit ...?? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Who's running a 4/6 drop kit on 20's? I'm about to pull the trigger on the ECE 4/6 kit. I currently have 17's all around with a 60 sidewall but thinking of going with a nice set of 20's.

It's all about wheel backspacing and overall tire diameter.
This is member 72BlkButys 69 on a 4.5/6 ECE drop.
20x8.5 and 20x10 with 255/40 and 295/40 tires.

That's pretty much the look I'm going for but I wondering if I do the 4/6 drop on my current set up it will be ok, then as funds permit I can get some nice 20's. Right now I have about 3 1/2 clearance in the front. Can anyone tell me if the 4/6 drop is a true 4" drop?

what backspacing do you need to run not to have any rubbing issues?

Every combo is different so there's not 1 correct (100% definite) answer.
