2" dropped spindle with OE hub would be perfect

 

I'd be interested in a set of drop spindles for the OE hub. I bought a set of SSBC brakes for my car and need the OE design. The drop spindle would be much better than cutting the springs.

 

Why not a lowering coil spring? Engineered to work at that height, I would trust that rather than cutting the coil and cobbling the spring.

 

Typical 550# front coils (a very popular rate) on offer for the C3 already lower front ride heights by ~1". As far as producing springs guaranteed to lower any particular C3 by an exacting amount, that would get into engineering custom coils for each individual car and its owner's desired height. Better to buy front coils off the rack and just tailor them to suit your own needs; which really isn't all that much more trouble than tackling the installation itself.

 

i have tvl on the front and would like to go lower but i am running out of travel.
1" or 2" would really help.i would like the OE hub

 

I'm in on both counts
I wish you could do 2" on the spindles , But anything is better than where we are today.
I was just about to mod a cross member this weekend
Hurry up Van Steel !!!
Building me a RAFT Racer copy !!

Might I suggest decaf?

 

Just a few days left to vote if you haven't already. Thanks for the input from everyone.

 

Is there a real benefit with the geometry or is it just for cosmetic reasons?

 

I voted for an OE hub.

Any idea when are going to be available? I am about to restore my front end.

 

Any progress ??

I will be one of the first when are available.

 

Rookie questions:

1. Would 2" drop spindles cause huge geometry problems that will not allow enough suspension RE-adjustment?

.......OR.....

2. Is it just a matter of retaining factory/near-factory specs on any drop spindles?


(I bought "soft" 330# coil springs knowing that the rate would increase after cutting coils...the "ride" is firmer now/just "right")

 

I would probably get a set of coil overs for the front. They would probably be the same price and then you have more of an adjustment.

 

I've looked into using dropped Impala spindles because the parts interchange manuals list 69-70 disc brake Impala spindles are the same as 69-82 Corvette spindles. I contacted 2 manufacturers of the dropped Impala spindles who both told me they will not work with the Corvette caliper bracket.

 

Other than unless the distance between ball joints is different, 2" drop spindles would only lower front ride height by the 2", thus lowering front CG and RC in the process. There would be no change to spring rates, caster, camber gain, bumpsteer, Ackerman, ICs, etc., but front scrub radius would actually increase. Adjustability shouldn't be affected, but you'd need to pay closer attention to outer tie-rod end clearance, especially if looking to increase wheel BS. (This steering arm link point cannot be raised to increase clearance without affecting bumpsteer.)


FWIW, tho drops appear to be a fairly straight forward way to go about lowering, I would urge doing so by conventional means (read, "reducing loaded spring heights") down to between 1" and 1.25" Z height - as recommended for road racing the Chevy Power Corvette chassis section - before considering drops, and to only consider drops only if intent on slamming to a point which would otherwise put Z at less than 1". Down to this point of diminishing returns, there are benefits to be had from changing the upper and lower CA angles. And, if you have the funds, coil overs would let you adjust ride height on the fly, while maintaining whatever proves to be your optimal spring rate. Which ever way you go, you still have the matters of caster and bumpsteer with which to deal. HTH

TheSkunkWorks.......thanks for explaining it.....

(and yes, I googled "suspension terms" to really understand.... )

 

Hey Bruce-

They (Impala) after looking into it a littler further- definitely won't work. Notice on the Impala- the top mount for the brake caliper bracket is parallel w/ the face- where as the Corvette is stepped back over an inch....AND it doesn't look like you could mill it back that much.

69-70 Impala w/ Disc Brakes



Stock 69-82 Corvette-

 

Already looked and tried the Impala spindles. The pin for the hub is for the smaller 63-68 hubs and you have to run a big brake kit. Early steering arms are the only ones that clear the lower a-arm as well. Late steering arms would have to be ground down.

The drawing for the spindles are just about done and we have to finish the steering arms. To get to where we wanted to be we ended up using C5/6 hubs. Once all the drawings are done, we will fabricate a few pair and do our final measurements and testing which will most likely be at Sebring and in Cali.

We are drawing something up to raise the inner TR ends.
