I guess I achieve the same thing by removing a portion of the top coil from the spring. Cost, nothing, effect's, no negatives and about 1/2 to 2" lower depending on how much spring is removed.

I did look at Freakride and if I were going to race or even autocross this car I would have gone that way. But I just wanted to lower it without moving the track out like with the drop plates. I am not a fan of cutting springs, these car ride hard enough as is. And I had already started this project when I found out about the coilover option. |

I've always heard the knuckle is forged steel. Is that what your fabricator found to be true? Did he tell you any of the specifics of his methods, what welding rod, welding procedures ? It looks like TIG welding. Edited by tyrodtom - Jul/17/2013 at 12:09pm |

Yeah they are forged.
He cut the added metal on his CNC and beveled both sides. He made a jig to hold it all together and tig welded them. His shop is http://fatcatfabrication.com/. He does a lot of high end race car and custom car stuff, probably why he is a bit expensive. I talked to him today and he said if I wanted more made the price could be a bit lower.

There are many ways to skin a cat, this is the way I choose. Certainly more expensive than I thought it would be, but I didn't want to give up suspension travel and make my AMX ride even rougher than it already does.

I got my front drop by swapping out my stock coils and shocks for a set of Shockwaves with custom mounts I fabbed up. I also had an issue with backspacing when I swapped in the 13" Mustang brakes that I adapted to use. The 1/4" thick plate moved my custom ordered wheels out a little too far for my taste. I ended up cutting off 3/8" off the back of the spindles. I like the idea of an all-in-one caliper mount, drop bracket. You could make one by tracing your drop bracket on some 3/8" steel then tracing your caliper bracket on the same plate before cutting them out as one piece. I like the idea of the custom spindle that guy made and it sure looks like a quality piece. I was also well into my custom front end before Control Freak came out with their system or I would have considered it instead.

Only T/A cars had factory forged steel uprights. Read the unfair advantage. I do believe they are cast steel. |

Narrow parting line = casting
Wide parting line = forging
Judging by your pictures, the knuckle is cast, the steering arm is forged.

Nice job! Wish someone would offer dropped spindles for a resonable price. Since he already made them, maybe your fabricator could now make a bunch of sets and sell them.
I've cut springs a number of times-just remember by doing so you do get a stiffer ride. Used the plates too, and had to go with smaller tires to prevent tire rub. Control freak is nice as is a few other vendors setups out there but then you're getting into $$$$.
