I was looking to get these, but are they worth to get? Do they resolve the problem on the axles with the pitting on the cv joints? or prevent any other problems that may come out, due to the axles being strecthed? bearings, hub, diff, etc? what are the pros? any knowledge of this product will be greatly appreciated. thanks

This is what they say:
The original driveshafts of the S2000 is design at the stock ride height so when the car is lowered with coil springs or coil-over suspension then the driveshafts will be stretched about 10mm each side. This will occur a lot of stress to the driveshaft. As a result, the driveshaft will wear down in a very short period of time. J's Racing offer this spacer which the driveshaft can be 10mm closer to the outter side of the shaft so the shaft will not be stretched. This also allows the driveshafts to have longer life.

 

They do what they are supposed too. It's not that complicated of a part. There are others available without J's Racing stickers that can be had for less.

 

the 7mm would be fine.

 

yea J's claims that approximately twice the life was realized
but other people make them too. spoon, and i hear even the driveshaft shop makes them too!

 

worth is is in the eye of the beholder but they will certainly relieve stress on CVs, bearings, etc.

 

Motorklasse is a vendor here and they make their own high quality driveshaft spacers.

 

comparing the two, J's offer 10mm, 2.5mm more than Motorklasse (7.5mm), will that extra give the axle more life? The price difference between both is about $50. Honda had fixed the problem by extending the joint about 10mm on the AP2. Motorklasse has there spacers to 7.5mm in the event that you can put the car back to stock height without removal of the spacers, is anyone of the two better than the other? thanks for the input. looking to get a set asap!

 

eh...make your own. Just find someone with a drill press or a machine shop will do it for peanuts. You'd just have to disconnect the shaft from your diff and make a stencil and take the measurement of the inner/outer diameter of the diff connector.

 

I got the J's ones only because when I bought my rims the seller had these so I got a good deal on them. My car is lowered with Eibachs and I recently installed these. Im at 70k so if an axle/cv boot wears out/breaks, who knows if these have helped since my car has been lowered for a long time and I have only recently installed the axle spacers.

 

better take it to a good machine shop.. cause remember, its a rotating part.. so it needs to be balanced as well.

but these do work, i found out the hard way.. my S was slammed,, and my cv axles went fast.
