Swapping over my 03 RX to a apex GT front end and the upper a arm bolts at the spindle are not long enough, I get like 1 thread showing. Does the Apex Gt use longer bolts?

Also I haven't tighted the bulkhead bolts yet but it appears I have a lot of side to side (front to back) movement of the a arms. It moves up to 1/8" each way, will that tighten up when I tighten everything down? Also the long bushings seem to stick through the bulk head by 1/16" of a inch so when I tighten them down the washer will not even touch the bulkhead because the bushing seems a little long.

I also noticed there is no lower a arm bulkhead bushing! Yikes.

Also the apex spindles look to add massive caster over the rx one, is that the handling improvement?

Thanks! :rocks:
 

Did some searching and it appears the lateral a arm slop is normal and may be less then most has expereinced, any issues if I shim them with washers so they are closer?

Also the bulk head bolt question is because there are no bushings installed on the lower a arms!! The bulk head appears to be ovaled very slightly. I removed the front bulk head bushing and test fit into the rear holes and it fits pretty good, I don't suppose there are over size ones? I could use like 1/64" more diameter. Once those bushings are in place the washer will sit flush and I won't have that issue described above. It threw me off not being familiar with that area and figuring out that BOTH sides are missing bushings!

I used the PP nylatron bushing kit for all over bushings and I was amazed at how much slop was removed from the almost new take off apex GT front end! Especially at the spindles.

Also looks like the apex GT upper a arm spindle bolt is a different part number and hopefully longer then the RX one so I will order 2 of those.

Thanks!

When using the Apex spindles, you must also use the Apex upper A-arms because they are a different length. If you don't, your camber angle will be way off.
 
Here is a pict of the bolt issue where a RX bolt will not work, port yamaha will hook me up thanks guys! ;)!

I used some of the nylon washers (once the cup was removed and they were thinned down a bit by sanding on them) to tighten up the A-Arms on my RX-1. This worked great. It stopped a banging noise I was hearing from time to time.

Possibly someone could turn you out a couple oversized sleeves out of brass and then fit a standard bushing inside the brass sleeves. Of course you would have to ream out the bulkhead holes a bit to accept the new oversize sleeves.
