I'm trying to find out what the difference is between a CRX Si hub and a JDM SiR hub. I know the disk size is different but what else, is there a different spline count? Are they compatible with the 90-93 Integra axle like the Si hubs are?

 

yes they are compatable, just get the integra ones they are the same ****,

 

the sir hub is pretty much the same as the 90-93 integra hubs, ad the 90-93 integra axles will work fine

 

are you meaning the whole knuckle, or just the hub? the hubs are the integra hubs, but the knuckle is the correct height.

 

the SIR knuckles have different tie rod steering geometry.

 

true, but can't you just get around that by shortening/tapping your inner tie rods?

 

i actually dont know what the difference is. i just know its different.

 

What are the size difference between the rotors on DA and JDM EF?
