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.

Any thoughts anyone??

 

Interesting!

 

are they talking about the propeller shaft or the two drive shafts coming out each side of the differential?

If its the two drive shafts, I don't see how they are stretched, as the hubs travel thru an arc dictated by the geometry of the control arms. Sure, rubber seal boots may crack or tear, but I don't think the shaft joints are being stretched at all.

 

i think that J's is referring to the (2) driveshafts (axles)

Possibly if the car were lowered to the extent that the bump stops had to be removed or cut down allowing the swing arm to go past the designed operating range. Only a guess, and yours is as good as mine.

 

Bump, i posted a thread in another forum. Can someone find out from J's or has any one had any trouble with their axle's or shaft?

 

PM Hecash, he is running a custom set.

 

When the suspension cycles through its travel, the axle shafts move in and out of the CV joints because the move in a different arc to the suspension arms.

For these to work, the axle shafts need to be pulled out from their normal position in the CV joints. What this means is that you are transferring the same torque across a much smaller surface area now (where the CV joint and axle shaft connect). This leads to greater wear because of the reduced area.

These spacers essentially change the arc the axle shafts make and bring it more into line with the arc the suspension arms make, thereby keeping a greater contact area between CV joints and axles.

Whether or not this is really a problem is anyone's guess.
