Are there any available spacers for the ISF? I'm planning on rolling my fenders, getting wider tires, and therefore need spacers to complete the look, maybe 15mm in the back and 5 up front? anybody running spacers?

i had spacers on my F and would never put on another set of spacers again....just get the right sizes and offsets and you're set.

 

I too, never recommend spacers with the "built in" studs for many reasons. They just aren't as strong. There's a lot of force and therefore stress on those parts to just rely on the built in extended studs. I've crack many myself, I've had many different brands with my STI, and they have all failed at some point. I will admit I am some what of a aggressive driver, I know my limits, I always say , Hmmmm Spacers are like driving with 3 lugs on each rim... You feel safe with that? Save ur doe, and get the correct offsets....

 

Agree with the last two posts...as a mechanical engineer, I cannot live with the reduced factor of safety of running spacers with built-in studs.

And here's another good read...

Spacers = for the IS-F..... or any car for that matter.....

Just my .02 cents..

I thought we already have some folks with wheel bearing problems. Spacers will only make it worse. But so will running "aggressive" offsets.

 

Thanks guys, saved me lots of money and problems that would occur in the future. Lobuxracer, running an aggressive offset will put a lot of pressure on the bearings? Since I couldn't find spacers I was planning to run wide tires in the back like 275.

 

^^^^You can do 275/30/19 on stock wheels. I'm running 285/30/19 Continental Extreme Contact DW in back on stock wheels.

I'm installing my KW's on Thursday over at VIP Auto Salon in Orange, and from there I'm going to buy some new wheels and tires, whats the farthest you think I can go without rubbing?

 

did you have to roll fenders? my stock tires are almost done for, so im deciding on what to do. i do drive aggressively and its my DD. i drive about 100 miles a day.

 

^^^^No I did not My thread is here:

Spacer = Fail !

 

Here's how it works - factory offset produces maximum wheel bearing life. Deviating from this reduces wheel bearing life, and the more you deviate the faster the bearings will die. It's not a big deal for a show car. It's a really big deal if your car is your only transportation, and you depend on it to reliably take you places.

No one can tell you how fast you'll wear out your wheel bearings. Anyone claiming they can predict this is very foolish at best. If you track your car, you WILL wear out your wheel bearings faster than someone who doesn't. If you run aggressive offsets, you WILL wear out your wheel bearings faster than someone who does not and drives the same way you do. Tracking with aggressive offsets is the devil's combination for bearing service life.

There is a place for spacers. Let's say you took a rear wheel from the F and wanted to put in on the front because it is an inch wider. You'd need a 10mm spacer to get the offset from +55 to +45 (the OEM offset for the front) and run the wider rim with a wider tire. Because the centerline of the rim is still in the right place for the bearing's calculated load, you can expect you'll get the longest service life from the bearing (but it will likely be less than stock because the rim and tire are wider which increases the lateral load's leverage against the bearing.)

None of this means you'll be stranded with a dead bearing and no warning 100 miles after changing your wheels. It means you'll reduce the bearing's service life by some percentage factor, no matter what. Whether it's 5%, 10%, or 50% will depend on a host of other factors, most important of which is how you drive.

That's the whole answer for bearing life. There are other considerations, like studs breaking and spacer's cracking, but again, no one can predict whether YOU will experience these problems without understanding exactly how you intend to drive your car.
