Shaggy wants adjustable camber for the track. I love the Racer's Edge units (of course, as they are stoopid expensive), but found these CHEEPOS on E-Bay.

Anyone have any comments about these, or other inexpensive options?

Pretty good pricing. I'd put larger washers on the bolts that hold the camber adjustment.

Keep in mind you'll also need to get upper spring seats, potentially, to use race springs. Not sure how well the stock upper spring seats work with any camber plates.

I bought them and didn't like them because they raised the front ride height by more than an inch. I removed them and went back to the stock upper strut mounts. I may re-install later after I am "adjustable" in the front end.

Did they come with instructions? Maybe they're supposed to install from the top?

This is pretty interesting, I'd def pick up a set if the ride height issue was solved.

No, they are supposed to be installed from underneath - that spreads the load to the strut tower. Otherwise you'll bend the sheetmetal. BTDT, like the sig says.

The problem is they're intended to be used with the adjustable front ride height setup (adjustable spring perch sleeves and racing springs). So bcblase has shown that they fit with stock upper spring perches, which is nice.

Sounds like I need to sell off some of my extra hardware...

What are you saying, boss? Got some plates for sale?

Adjustable height setup, not plates; one is a pair of stock strut bodies, with Koni yellows installed (used, think they're still in decent shape) and adj. height sleeves. To install and use on an existing car will require a pair of springs (think I still have a pair, 350 or 400, around, might make a deal) and upper spring seats (don't have those, will have to be bought).

I also have a pair of just the sleeves with seats, suitable for install on an existing pair of struts. As with above, will need springs and upper seats for complete installation.

Ground Control has a complete front and rear suspension setup for our cars. $1400 and you get camber plates, custom valved konis F/R, and adjustable spring seats. Sounds like a heck of a deal to me, especially since it basically drops in.

I know some of my Fiat friends use Mustang camber plates and just make them work for their use. Oh and you can put the camber plates on top of the struts, you just need to make the strut tower stronger. Either way, you'll want adjustable spring perches to set the base height and to help shift static weight between corners.

Keep in mind that aluminum work hardens over time and will become brittle, so if you race a lot you'll want to keep an eye on aluminum suspension parts.

Yeah, but I'm seriously underwhelmed by Koni performance. See the other shock thread (sticky) - better options exist for the same money, IMO...

True, but a matched set is sometimes better if you don't know how to spec out the parts yourself.

So you're saying you used this particular set of shocks/struts, with the valving they spec'd and the springs they spec'd? According to their description, these are valved different than standard Koni's for the 944 series cars.

Personally, I'd rather have something that is at least adjustable for both compression and rebound. However, that is only good if you know how to adjust the suspension.

No, I've run the street/sport ones... but they're still cheap twin-tubes. I've also heard less-than-stellar things about the GC shocks (not the Konis, their own brand). The Bilsteins, by comparison, have been super-durable, like capable of lasting years on a well-used racecar.

Same results comparing with others in ITB; they've tried Konis, even custom-valved units, yet they end up only lasting a couple of weekends before needing service... these guys are all running Bilsteins now - top 6 cars in my class at the ARRC (our de facto national championship), including me, all but one were running Bilsteins... That should tell you something! They also all blew away the previous lap record set by Randy Pobst... sadly, I was just over that mark, but very close...
