I read somewhere about needing driveshaft spacers if you are driving a lowered S2K. Something about once the car is lowered, it stretches/extends the driveshaft an extra 10mm since the design of the driveshaft was mean't to be used at stock settings. And if the spacers arn't used the driveshafts wear out. So is this true?? I know that J's Racing and T1R sell these spacers, but what do you guys think

I think its really for AP1s

 

after i posted this i read a couple hours later about the AP2 driveshafts being 10mm longer then the AP1s. Yeah cause thats the last thing i'd want to happen after i just got the car....it doesn't even have 12K miles on it yet and its a 04

 

Where is this stuff getting posted?

They are NOT 10mm longer. They are the same part number. There is a thread on it, in this forum on the first page.

 

For what it's worth, I've been lowered about 1.75 inches all around for about 10,000 miles now and have had no problems without running driveshaft spacers. Maybe some S2000s will develope problems, but certainly not all, as I've seen some people/companies claim.

 

Since the wearing out of the cv joints seems to be common for S's with unmodified suspension as well would there be a benefit to putting the spacers in to prevent the cv joint from wearing out?

I have pitted cv's, and i'm not lowered. Would it be preventative to put in the spacers?

 

I think all posts that say the axles are longer should be deleted.

 

Back to topic. IF lowering the car casues the inner cv joint to ride 10mm more toward the outside of the bucket, then the spacers are a good idea. They will effectively shorten the axle, and cut down on torsional vibration that could damge the axles, AND the dif.

Think of a drill with a short drill bit. Spin it fast, no problem. Now take a 1/4 drill bit that is 2 feet long and spin it fast. Torsional vibration will set in instantly.

 

so i'm guessing that it would be a good idea to get them???

now which ones, the one piece j's or the T1R half spacers which is pretty much the same thing as the j's just two pieces.

 

Well the T1R spacers are not yet available. So that leaves the other. J's is not the only one. So pick the one you want. They all do the same thing.
