Anyone have any experience with hamburgh technik caster mounts (updated 968 style)? ZIMS has them for $50 ( http://www.allzim.com/cgi/sh000001.p...341_2e023_2e01 ). I know Sunset has them for about $70.00 each, but was curious as to people's opinions on the HT units.

Thanks
Mike

If they are anything like the rubbish short shift kits that same company sells on eBay, I'd stay clear. Kinda odd Zim's would sell their products.

I can't compare them to the factory units, but i have them on my car and they've been great. Have read other similar reviews (all basically saying that everything else the company makes is crap, but the caster blocks work fine).

I think i paid $90/shipped on ebay for a set.

dykaar

I got a set off ebay as well. That $49 may be per side Vs. $85 - $90/pair on ebay.

I had an issue getting the shaft into the bushing. I should have removed the paint (I didn't), just pressed it in and it made adjusting the eccentric a pain. Haven't tracked it yet, buts it gotta be better than the giant rubber originals that had split sometime in the last century...

I spoke with the guy at ZIMS, he said only issues he had has with the HT units is that the shaft might not go into the bushing on SOME units, and that you may need to emory cloth it a bit. Exactly like dykaar said. Doesn't sound like too big of a deal. I'll give them a shot, the car is not a track car so I'm sure I wont notice the difference.

dykaar

If your bushings were the originals and 15 years old (like mine), I think you'll notice. Mine had split allowing something like 1/2" of movement. OK, maybe they got like that at the track, but you're reducing the amount of rubber from 1/2"+ to ~1/8". Thats gotta feel better, even on the street.

I have a set (technically, mine are from dp but they're the same yellow zinc ebay specials at ~$80 for the pair). I did the driver's side first, and it was a very tight fit.

In retrospect, I likely should have greased it a bit better. My passenger side block went on quite easily once greased, and I had no trouble putting it on with a C-clamp, then using the retaining bolt flipped over to push it on the last of the way. Not much force needed.

They've held up well to one season of track use, so far.

Expect your caster to change a little, no matter how you mark things because the new blocks are somewhat taller than the old ones. Oh, and as you've likely already read, DO NOT over-tighten the two bolts which hold each caster block to the belly of the car, as they basically thread into sheet metal.

Doesn't anyone use torque wrenches any more? The Porsche technical manuals give the torque values for the parts for a reason. When I'm installing new parts, I don't turn a bolt til I know what the value is. Saves a lot of headaches, like snapping CV bolts in the transaxle, for example.

LS1Porch

I just use common sense. It saves me hours of looking up torque specs, and has yet to fail! Of course, it's not as commonly available as a torque wrench...

pontifex4

I do, but not everyone who needs to do this will have access to one, and I was offering general advice on why it's important not to over-tighten them.

dykaar

I routinely find myself in situations where a torque wrench won't fit. The inside of the front control arm bushing for example. No way without a lift.

smokin_944

Charlie, I understand what you're saying. The reason I brought up the torque wrench is I just finished redoing the CV joints on my car, and I used new Porsche bolts on the install. I had one snap at 28 ft-lbs of torque when the specs say 31ft-lbs. That is why I am nervous about doing it by feel. Feel and common sense wouldn't have mattered in this case. Doug, I agree there are tough situations where the TW won't fit. That's why sometimes I have to rent some time at a garage to access a lift.

If it takes you hours to find a torque spec....
