So they would not work? (Sorry noob here) lol

Chump408

Yeah they won't work. Make sure when you're looking for spacers that they are for Lexus IS. Bolt pattern may be the same for a lot of makes, but the center bore differ from them. So make sure you purchase the correct ones.

I would highly suggest purchasing through one of the forum local vendors. Solid designs on them.

That's good to know and the prices on those you linked me to aren't bad. Are they good quality ?

Chump408

Yes I would say so

to guys that running RSR down springs and 20mm all around spacer, please answer me some question
1/ is it shaking when you drive at high speed
2/ is it really safe when you drive fast on freeway because i have read some article that mention about spacer cracking
3/ what brand is good brand ?
4/ do i need to alignment again after putting spacers on ?

Chump408

I haven't noticed any shaking on mine. I would say it's safe to drive during fast speeds as long as you buy a reputable brand such as: ichiba, h&r, b2autodesign to name a few. I would stay away from cheap brands. As for your last question, I do not believe you need an alignment for just adding spacers.

1. no, make sure you get 60.1mm hubcentric ones
2. yes, the safer ones are the spacers that have bolts sticking out (type 2)
3. i am running eibachs
4. no

For anyone running the "Type 2" spacers, did you shave down the factory bolts or replace them with shorter ones?

Where do you order them from? Ebay?

I put my Eibach spacers on a month ago and they are solid. I checked the torque specs after 3 weeks and they were still as tight as the day I put them on. I still don't trust any other cheaper versions.

I've done 110mph with them on a deserted stretch of road.

did B2 designs stop selling 20 mm spacers? only see 15 and 25 here?

kamranx5

anyone here with Tanabe's running 25 mm spacers in the front? I will be getting 20 mm spacers in the back which has seemed to work out for most people here but stuck between 20/25 in the front. I have a RWD if it makes any difference.

I have stock suspension and I rub in the rear with 20mm spacers. 15 or 18 would have been better.

It rubs where there are dips in the road or bumps.

Yes I had to shave the lug studs, I used an angle grinder and a file to finish up.

I am running 15mm B2Designs spacers on the back wheels of my car, yes my fenders are rolled and I still rubbed like all get out with new tires. There is about 6mm of useless metal right at the tip of the lug stud it has no threading and really served no purpose to me. So I shaved it down by exactly 5mm and left a nice smooth rounded tip.

The Fsport wheels have a nice little dimple in the back where the studs go so DO NOT cut the studs. just shave a only 5mm off! After you shave 5mm off you will be able to mount the wheels and they will sit flush on the hub centric spacer.

I used a caliper to measure each stud but I am 100% positive that was overkill and a waste of time since chances are they don't need to be exactly the same that close to the hub. .005mm difference will not cause vibration.
