GKTech - 10mm axle spacers - AXLE-10MM

>

Will these fit my car?
If you are unsure please measure the spline on your axles but unless your car is a GTR or a Z32 TT, or you know it's been upgraded then it will most likely have non GTR/Z32 TT axles (it's an expensive upgrade so isn't all that common).  

Do you make these in other diameters or widths?
We're not making these in any other sizes at this point in time. 

Do I need these?
If you are moving your hub out for any of the following reasons: running a dual caliper bracket, you're running extended LCA's or you're running an S14/S15 subframe in your S13. Ideally the amount that you're spacing out your hub, you want to space out your drive shafts.

How do these compare to the bolt on kind that you used to make?
The bolt on kind under high loads was prone to destroying the supplied grade 12.9 hardware. The slip in spacers don't have this issue however they do reduce the spline contact between the axle and the hub. Ie. the spline is 2.36" (60mm) in length so if you add a 0.19" (5mm) spacer then you're reducing the spline contact by 8% or going to the 0.59" (15mm) spacer reduces the contact by 25%. This shouldn't be an issue for most cars but there is the increase in chance of stripping splines (albeit we haven't seen it happen).
