So I'm about to order a set of 5mm spacers to get my 18x8 ET40 flush flush with the rear fender. I came across this note on the ECS website and was wondering if anyone has 5mm spacers and can confirm that they will stay hubcentric.

I've got 5mm spacers on the rear, and I'm pretty sure they don't have a hub extension (which would make them hub-centric). However, I didn't install them, and despite the many times I've dismounted and mounted wheels, I haven't looked at them particularly closely.

If you can't get a definitive answer here, you might try an independent - say, like Pacific Motorsports 503-278-4271. Come to think of it, ECS should be able to answer your question for you.

If you get desperate, I'll remove a wheel and take a picture for you.

Haha thanks but I'll eventually get my wheel off to check it out. It's just been bad weather and my garage is too cold at the moment. ECS currently has a 10% off sale on spacers but I can wait.

I am interested in knowing this as well. Here is a post by B58togo:

"I have 5mm ECS Tuning spacers with my Apex EC-7's and I'm not losing sleep over any possible negative consequences. They weigh nothing, car rides smooth, and realistically, since the wheels are around 4lbs lighter each than OEM wheels, it's a non issue. Of course, when I go to put the OEM wheels (with Pilot Alpin PA4's) on this weekend, I'm sure the spacers will be stuck to the hubs, so I'll just run them through winter. Now if you're running 30mm spacers with heavy 20's and you're slammed with -4 camber, there may be side effects."

Still no problems. I run the spacers with the EC7's April to November and with the stockers November to April.

Thanks for the confirmation. So after the 5mm spacers, how much extra length of the hub is protruding? I'm thinking 2-3mm?

that’s right. 5 mm are kind of dicey depending on the wheel design you use. the hubs may in fact not protrude enough to keep the wheels hubcentric.

I used 5 mm spacers with stock wheels and there were only about 2 mm on which to center the wheels which could easily have been a problem should I had hit a serious pothole or something. I can imagine I could have easily damaged the hub or the whole assembly. Just didn't inspire too much confidence.

Looking at the back pad of different wheels I can imagine there may be wheels that won't work, won't center, with 5 mm spacers.

It's not just how much of the hub is protruding it's also about design of a specific wheel.

Thanks for the input. I'm on 18x8 ET40 and I'm just about 5-7mm from the fender to sit super flush. Maybe I'll pass on the 5mm. I'm tempted to go up to 10mm but that would give me a 3-5mm poke. Still debating if I want to go this route.

to be clear: there is more mm protruding but there is only about 2 mm to actually center the wheels on (where the inner bore of the wheel back pad has contact with the protruding part of the hub). also, it's a good idea to try new wheels first to see if they work with 5 mm spacers.
