Just a few quick questions. I am looking into 2" drop spindles for my 70, do most of these applications bolt up to an otherwise stock suspension? Also i have heard questions on these spindles working with certain size wheels, i plan on alteast a 18" wheel, does this create a problem? Also, with using a drop spindle, i assume that a drop spring should be used? Last thing, i purchased a disc brake conversion kit, it came with stock height spindles, can the calipers and the rest of the kit still be used if i was to purchase the lower spindles? Thanks in advance. Josh

Follow the links to pictures of my car with 2 inch drop spindles and 18 inch wheels. The 2 inch drop spindles are a direct bolt in. I used the stock springs up front and 1.5 inch drop springs in the rear. I believe the brake conversion kit is also a bolt in job. I ordered my two inch drop spindles with the disc brakes already done.

Might wanna read the Hardcore Suspension thread in the Pro Touring section and the Tall Spindle and Bumpsteer thread in this section before you invest your hard earned money. Don't know about you, but I always like to get educated before I buy anything.

Ok, i checked out the threads suggested, now i have a pretty dumb question..but i just wanna make sure i get this. The 2" drop spindle for A body cars is actually a B body spindle? or are these two seperate ways to lower stance. If they are the same, and the bumpsteer issue is such a big deal, what is the next best way to get the stance and handling advantage over a stock A body spindle? If they are different, do i have to worry about the bumpsteer problems with the A body drop spindle? Thanks again Josh

The 2" drop spindle for A body cars is actually a B body spindle?No. The "B" spindle will result in about a 1" drop if that much. True dropped spindles are stock spindles with a 2" dropped pin. The older ones got it all wrong and screwed up the steering geometry. The newer ones do a better job with the steering arm.

Are these two separate ways to lower stance. If they are the same, and the bump steer issue is such a big deal, what is the next best way to get the stance and handling advantage over a stock A body spindle?The best way is via dropped ball joints and lowered coils. This will easily allow a 2" drop with no ill side effects.

If they are different, do I have to worry about the bump steer problems with the A body drop spindle?Yes, even the Fatman and Heidts spindles have some bump steer issues, not much worse than it came from Chevrolet with though. Thanks again Josh

ATS also has a spindle available and the steering arm is due for release anytime now. It is a little pricier than the other options but seems to be the best alternative for a true bolt-on approach. It has a 7/8" drop and with the dropped ball joints you would have a 1 3/8" drop. Some shorter coils and good shocks would give you one hell of a handling machine with the height you are looking for.

Dennis,
Are the Superior drop spindles the "older" ones with steering issues? I have a set with 12" brakes that I want to use with SC&C's stage II kit. Marcus did say I can use the spindles, I just want to know all the facts up front. I compared the steering arm position relative to the stock ones and they seem to be in the same position, other than the tie rod hole being rotated toward the inside, probably for wheel clearance (15" are rather close, 16" have slightly more room). Thanks Randy

Yeah, the Superior Spindles are from the days before we (the enthusiasts) demanded a better product. The steering geometry is not the best. I would not say it’s as bad as the "B" spindle is but it leaves a bit to be desired. An interesting test would be to install them and run a bump steer test so we can see how far off it is and how closely it can be corrected to zero.

I should have enough parts here to do a bumpsteer test next month. It will be interesting to see. The tie rod hole has already been drilled and bushed for use with heim joints by previous owner (had rack & pinion), so I should be able to make changes. I will post the results later. Randy
