alterkation front end? how are they?

They are what they say they are... absolutely the best! At 116MPH on the track the stock steering tends to be a bit... well, I guess the best way of saying it is loose. You'll find it wandering and a bit less than super reactive to input even thought I had installed all new parts and urethane everything it still tended to be a bit loose at high speeds with skinny front tires. I always had the car aligned with the nose up 2" to compensate for the body lifting while on the track. But it did what it did.
I put on the Alter-K-tion set up and VIOLA! No more wandering. It goes where I point it, input is precise and deliberate. We're now running 125MPH and it is still a fantastic investment in control and stability. Bill really did his homework on these and he doesn't get the credit his stuff deserves. I also run the same car with a different engine on the street for GP (General Purpose) driving and it still has wonderful street manners.
Disclaimer: Mine is in a 69 RR all manual with Wilwood brakes and no sway bar (one of Bill's early B body models). Had I been making the same money I was then, my Dart would have the same set up too.
Just for giggles, I weighed the parts going on vs the parts coming off and I lost 86 lbs in the upgrade. I got gobs of extra room for getting at things too, It's not nearly as cramped in the engine compartment so dealing with bad starters or headers is soooo much nicer.

...and unlike some other brands I've heard of, I had no fitment issues what so ever on the install
