Where to get wheel spacers for IS350??? (Update & pics on pg.4)
 

I've been searching my fingers off, and I can't seem to find anyone who makes or sells wheel spacers for the 2IS. I know the bolt pattern is 5 lug x 114.3 (or 4.5"), and the center bore is 60.1mm... I have two questions:

1. Does anyone know of any brands or companies that manufacture wheel spacers for our 2IS's?
2. After looking at the specs for the 1IS, it seems that those cars have the exact same bolt pattern and center bore size. Can I buy a spacer marketed/designed for a 1IS and expect it to fit my 2IS?

Thanks in advance,

Javier

*EDIT* You can find pictures and a brief write-up of my spacers on page 4 of this thread.

i am in the same boat as you, i heard that we would need hub centric wheel adaptors and not spacers.

hub centric rings and wheel spacers accomplish two different things, spacers is to correct offset of the wheels so it will fit better for your car, the hub centric rings are to compensate for the larger bore of most aftermarket wheels (so they will fit a larger range of vehicles) so the wheels dont vibrate

most likely we can use the H&R spacers that the GS and SC owners use. how many mm did you want to try and push the wheels out?

i just looked on the H&R website and they have hubcentric spacers available for the GS that should work on the IS. they are available in 5mm, 10mm, 15mm, 20mm and 25mm. hope this helps..

Oooh, that's a GREAT idea - thanks IS 250!!! :thumbup:

You need wheel spacers that are hub centric though to prevent imbalance. If you buy the cheap spacers from Pep Boys which are not hub centric, it will be impossible to get them to fit dead-center on the hub which will make the car feel like you've thrown a wheel weight or bent a wheel. H&R builds hub-centric spacers...definitely the way to go instead of the "one-size-fits-all-but-doesn't-fit-well" junk sold at the auto parts chains.

One other thing worth mentioning in this thread...it's imperative that the lugnut bolts be replaced with longer ones when spacers are used. Simply measure the length of the stock bolts, add the thickness of the desired spacer, and that's the bolt length that should be used with the spacers.

avoid using spacers~ use wheel adapters

Hey IS 250 - I just looked on the H&R website (www.hrsprings.com) and I couldn't find the specific application for the GS - where did you find them? And does anyone think the spacers/adapters for the 1st Gen IS would work?

Javier

they should work... when i went on the website i entered info for a 2003 GS and it came up with info the the Trak+ spacers. There should not be a problem since the only thing you need to match is the center bore and bolt pattern. as long as the 1g IS has the same center bore and bolt pattern they should work as well.

Yeah, I noticed that the part #'s for the '03 GS and the '05 IS are exactly the same - I think I'm gonna try this out. Thanks for the quick reply!

Javier

my work bores me... CL is the only thing that keeps me sane. post some pics up when you get it all worked out.

I just got my spacers from ICHIBA. I got 25mm. Here's their website ICHIBA

The IS300 spacers WILL fit the IS350. I just installed a pair of H&R 5mm spacers on my fronts. The part number for them is 10656014, and they do come with longer lug studs. I'm currently using the spacers without the extended lugs, but not for long. My lug nuts are only using 3.5 threads! :EEK:

DAMN! What could you possibly use 25 mm spacers for?!

This didn't go on my 2nd gen IS. I put it on my 1st gen IS. IS300 spacers WILL fit the IS350.

Haha, I was looking at that site this morning... I called them but I guess it was too early. I'm actually ordering some 25mm for my rears - the offset (for stock 18" wheels) is quite extreme once you drop the car. The gap from tire to fender is a tiny bit over 25mm.

Javier

Are you usr its about 25mm on your rears? Seems quite a big gap? Post pics please. ..

I think your measurements might be off. If I remember correctly, the stock rear wheel has a 50 mm offset, and a 35 mm offset winds up being VERY close. I have a 18x9 with a 35 mm offset and stock tires, and I can't believe it doesn't rub.

Considering the fact that you will have to put much longer lugs on it to even do a test fit (a major PITA), I would reconsider the plan.

Thanks for the replies, everyone... I have no idea what the stock wheel offset is, but I was instructed to measure the distance from the tire to the fender. I taped a piece of string to the fender with some washers tied to it to create a plumb line, and measured the gap from the tire to the string. Did I measure wrong? I got 20mm for the fronts, and 25mm for the rears. Thanks,

Javier

Did you do this? How To Measure?

The widest point of your tire and wheel combination is usually the outside diameter of the tire sidewall. Using a ruler with the straight edge flush with the face of the tire, measure the gap between the outer face of the tire to the inside lip of the fender as shown in the diagram. This will determine the thickness of the spacer you will need.
5MM = 0.197 INCH
8MM = 0.313 INCH
10MM = 0.393 INCH
12MM = 0.473 INCH
15MM = 0.590 INCH
20MM = 0.787 INCH
25MM = 0.983 INCH

Were you measuring to the inside of the fender liner to the outside edge of the tire? The outside edge of the fender (painted surface) really doesn't matter.

Ah, I measured to the OUTSIDE of the fender - this will probably add 5mm to my measurements...

Javier

so can someone give the amounts of what one would need to get to make the stock 18s flush with the side of the car. i would like to purchase these right away.

I measured 15 mm from the outside to the inside of the fender.

10mm front and 15mm rear would be the most you could do and definitely not rub with stock wheels and tires.

I'm measuring my stock rims (front and rear) and I measured 15mm. I'm not sure if this is the right number can anyone confirm this?

So I'm 5mm off at the front. Thanks:thumbup:

Javier can you post pics

so 10 and 15 mm would make the stock wheels flush. thanks alot. going to order these tonight.

The reason why there is a 5mm difference between front and rear is because the fronts actually pivot, and the rears don't. If you want the front and rear to look equally flush, do 10mm on all 4 corners. If you do 10 in the front, and 15 in the rear, the rear tires will be more flush than the fronts.

would there be a problem using spacers on AWD???.....coz the rear tires on AWD is the same as the fronts...so the gap from tire to fender is even more....i think i would need to use 20 or 25mm for the rear to make it flush....i hate the indented look of my rear tires:mad:

I'll take some pics when I get home from work and post them tonight.

Javier

Cools. . . .

so 10 mm for both front and rear?

Awww javier, i thought you got rims or something.. spacers for your stock rims... booooooo.. buy mine :) hahaha

What are you asking?! If you want the front and rear to be MORE flush, but also EQUALLY flush, then yes. If you want the front and rear to each be as flush as possible without rubbing, the do 10 on the front, and 15 on the rear.

BTW, I don't recall H&R offering a 10 mm spacer.

awny place online to order H & Rs?

From my knowledge, no. Because the only difference that would cause a problem on a AWD is the overall diameter of the tire that touches road surface. This creates more/less resistant and could cause overall stress. Also weight could make a difference too, again more/less resistance. But spacers only push out the wheels further and can't make a dramatic weight difference that could cause any problems for a AWD. I'm thinking of getting a set myself, but I'm waiting for a custom set to be made and the guy that makes them isn't in town lately.
