I am assuming this is a RWD, would this spacer set up be recommended for AWD IS350 F Sport, or would 20MM or 25MM square set up be best? But absoluetly love the look of this right now!

Hey guys, new to all this and trying to follow this extremely long thread is a bit difficult. So far, I'm getting that the 2 top brands for spacers that don't cause vibration are Eibach and H & R, but when I go to their website I can't find for my car 2014 AWD IS350 F Sport. I only seem to find options for RWD. I have the F sport stock rims and stock suspension, and from this thread I'm noticing that 20mm all around doesn't rub. Can anyone that has an AWD let me know how you found your spacers? Thanks guys

I know this is an old post, but I too have same year and model with stock rims and suspension. Have you noticed any vibration or rubbing? Thank you

i'm using "generic" from amazon and doesn't vibrate whatsoever. see my post

There's little risk of vibration so long as there's no debris between the rotor and spacer and on the wheel. the spacer itself is machined so its going to be flat. surface preparation (cleaning/sanding) is more important to avoid vibration, more so than brand. also make sure (they all do)they have strong grade 8 bolts.

I put together a wheel clearance calculator in excel and based on fitments I have compared there is approx 1" (25mm) in the front and just under .9" (22mm) in the rear to fender. I have not tested this yet but the more fitments I test from members, the more it confirms my findings.

20mm spacer in the back. This all the way down with the stock tires. *for testing purposes
It will ultimately make contact with area where the bumper meets the rear arch.
If you have tires with a lesser sidewall thickness it will clear.
If your springs are too low or too soft it will rub there under the right conditions.

What is actually rubbing here? The fender or the fender liner?

With air suspension aired-out, would the rim clear with 20mm spacer?

Your rear tire is 255/35/18?

Does anybody have a picture with 20mm at the front and 15mm at the back on stock height with stock F Sport rims?

Depends when you rub. If its driving straight but hit a bump it shouldnt matter since when you hit a bump the springs will compress to a size similar to lowering springs and the suspension geometry will essentially be the same including increasing camber upon compression. If you rub when cornering hard then the lower height may be more of an issue.

I'm thinking the reason some are rubbing on 25mm/20mm spacers is due to tire size rubbing. It's probably best to go with a size narrower than the oem tire. Some people here may even be a size wider. This thread would be improved if everyone posted their tire sizes too.

Hi guys new to this, have a 2016 is200t base RWD with fsport 18 inch wheels and stock suspension, what spacers do you recommend to not have any rubbing.
thanks

20mm all the way around will look nice and not rub. I'm only half lowered.

Also update: new Meyle rotors. replaced those noisy drilled/slotted stoptech rotors. god the new rotors feel like glass. had a nice coating on them too. Go Meyle! Combined with brand new German Pads (stock)

I gave everything a good clean, sand, lube between shim plates and pad "ears" where they contact the caliper block. Calipers torqued to spec. Everything is perfect. I think these Meyle rotors are new on the market cause I've never seen them before. But from past experience, Meyle is a good aftermarket company. Brand new front set for less than the price of one genuine rotor.

Here's 20mm on my rear with 255/35/18 (stock tire size and stock F sport wheel). It's about perfect. This is with Tein H Tech (very conservative spring less than an inch drop)





My fronts could go "out" maybe 3 or maybe even 5 more mm, but it's acceptable.

That's a nice drop. Drop springs or coils?
