Been browsing the forum for quite a few years now and finally getting around to posting something. Just got my 68 chevelle back on the road a few days ago and am ready/able to put the time and money into her that she needs.

Currently running a stock power disc setup that we swapped over from my 70' Chevelle after it went down in a blaze of glory (literally, electrical fire in the drive-way shortly after we got it).

I just had my new rims/tires installed yesterday (been sitting in boxes for about 4years) and my next focus point is the front suspension. I'm looking into the SPC adjustable upper arms and the tall upper and lower ball joints in the SC&C Stage II package. My father voiced some concerns regarding his past experience with extended ball joints breaking (granted this was many years ago). Anyone have any experience with this? Or evidence to show otherwise?

Also, the SC&C site says the arms allow for more positive caster. Currently I am at -1.4L/-1.6R which is far from ideal, but it would appear that not much can be done to adjust that with the stock arms. How much caster do the SPC arms allow you to dial in? Is it adjustable, or is there simply a certain amount built in? I'd like to get a couple degress of positive caster at the minimum.

I'm ready to get my hands on this stuff, any help is greatly appreciated.

The tall ball joints are just that, tall ball joints the stud is longer they do not use extenders . These type of ball joints are used in circle track racing quite often so they should hold up to everyday driving The SPC arms are fully adjustable do a search for SCandC and you will have most of the info you need. Marcus at SC&C is a member here and will probably chime in when he sees this.

Thanks for the info.

I've already looked through the SC&C stuff as I said in my post and was looking into their stage II kit.

I can't yet report how the Stage II kit works on the road, but the parts are of incredibly high quality and installing them encountered no difficulties at all. If they work as good as they look, this thing's going to be a ball to drive. Marcus at SC&C is a gem among service/product providers and a wealth of information. As a bonus, he drives what he sells and can tell you exactly how things will work, not work and how they will hold up over the long haul.

Cool, I'll be calling over there when I get a chance.

Other than that, with the amount of people apparantly running this stuff there has to be some more information/feeback related to my original questions.

Howe Precision ball-joints are not your typical Auto-Zone parts. The quality and strength is simply the best on the market.

Yeah and they are even rebuildable. Those things are high-end stuff.

Had a chance to speak with Marcus for quite a while today and he was able to answer all of my questions (as I assumed). I ordered the Stage II Plus package and will eagerly be awaiting it's arrival.

For anyone who was curious about the questions I asked I'll provide his answers.

In regards to their strength, they are built to hold-up. Even though they are "taller" they are still shorter than the balljoints equipped on some trucks from the factory, and are very different from the ball-joint extenders many people used years ago.

The caster as well as the camber is completely adjustable via the arms and allow you to run pretty much whatever you want. I knew the camber was, but was unsure about the caster.

Many people I'm sure already know this information, but I am providing it here to those like myself who were not able to find a clear-cut answer regarding these facts through a mere search of the site.
