Has anyone installed the ATS spindles with SC&C upper arms, and 17" wheels?

If so, what backspacing are you running, and how much clearance between the control arm and the wheel?

I am thinking of going this way, but I want to run 6.0" of BS on a 17" rim (I previously did this to fit 17X9.5 and 275/40-17s under the front of my '66, but "stock" spindles/BJs)...


Any ideas (Marcus?) of the height difference (spindle pin to upper control arm) between Stage2 and ATS setups?

Thanks...

I see that brake packages for the ATS spindle are a little less than the same brakes for "stock" spindles. That help offset the cost of the ATS pieces...

Tony - I have now have that setup with 17x9.5 with only 5.5 bs. It would have been fine, but the rims I bought have spokes that curve in towards the caliper - which is a problem. I need .75" of adapter to clear the caliper, Which means 5.5 of BS probably won't work for me any more.... I wish I had your 6.0 bs!

I'll have answers shortly for you Tony... I have ATS spindles, SPC Pro-Lite uppers, and C6 brakes inbound as we speak and have 9.5" wheels with 5.5" of backspacing. Hopefully I'll have everything in-hand next week.

The biggest problem with the C5/C6 brakes, as mentioned, is that rotor offset is minimal. This pushes the caliper out closer to the wheel. Checking with a couple of templates (Touring Classics & Kore3) I'm only expecting 1/8" of clearance between the caliper & back face of my wheel spokes at the tightest spot. With my old Torq-Thurst II's I would have needed quite a bit of spacer to clear C5/C6 brakes. Most of the "vintage" looking wheels for our cars don't have necessary spoke clearance and require a spacer of some sort, which will obviously affect your backspacing.

I have the the ATS spindles, SPC pro-lites, 13 in. Eradispeed rotors, and C5 Corvette labled calibers. Currently running 18" x 7" with 5" backspacing. As Troy mentioned, the clearance to the caliper is very tight. Might be able to fit a 17 inch wheel, diameter wise, but the clearane to the back face of the wheel is the issue. I've run a 17 in Junkyard Dawg with a spacer. Other than that, everything else fit fine.

On my last car, I did run a thin spacer (thinest Mr. Gasket, under 1/8"). I was running the C5 (non-Corvette script) calipers, which were very close to the calipers without a spacer (might have actually rubbed, but I installed the spacer first, to avoid blemishing the nice anodized calipers)...

I was running Vintage Wheel Works V40s.
In my case, the spokes were close, but also a center-section lip where it was welded to the barrel of the rim...

Honestly, when I ordered the wheels, I was anticipating the old "tall B-body spindle", with an increase track width (but never installed that swap)... But the BS worked very well.

Stock spindles, Hotchis 1" drop springs and the only "rubbing" was on the sway bar (1-1/4") at full lock...


So, effectively (because of the spacer), 5.875 or 5.75 inch should work fine (assuming the spokes cleared the calipers)...

Radially, my wheels choice was also very close (not sure if C6 calipers will still clear, but always an option).



BUT, because of the drop spindle, I was wondering IF the wheel will clear the upper control arm...

Thanks,

I look forward to hearing more (and maybe Troy will be attending the BBQ after the TnT???).

Mike, I see you are from sacramento too... Hope you'll join us too... Check the "Team Chevelle Cruis-in" forum..

Plan right now is to be there. :)

I'm putting my car under the plasma cutter this weekend (too low-- 4" driveshaft hits the tunnel, had to put bumpstop risers in as a temporary fix.) Solution: cut tunnel completely out and build a new one. I should have that done in 2-3 weekends, about the same time I expect all my parts to arrive. The ATS steering arms are on backorder but Mark expects them in this week, so figure 5-6 days on the UPS truck from PA to CA.

I also have a slightly drippy waterpump to block gasket to swap out. Wouldn't be such a PITA without all my blower piping and junk in the way.

Thanks for the invite, Tony. Yeah, I'd like to join you, but my car is still apart after paint. May take me until summer to get it together again.

No Chevelle required... Both my Chevelles need lots of work, but hopefully I'll have my '70 ready to race (fuel line, ignition box, new sticky tires, new guages)... Alot of stuff needed BEFORE the TnT though... I am going to try to get some stuff done this weekend, I just hope the nice weather sticks around...

Everybody is more than welcome to come race or just watch and hangout with us, and even if you can't make the races, you can always swing by my place to hang out, BBQ and BS later. I promise not to force anyone to work on my cars (although, maybe I'll get Craig to offer some gentle "persuasion") ;)...

Has anyone installed the ATS spindles with SC&C upper arms, and 17" wheels? I am thinking of going this way, but I want to run 6.0" of BS on a 17" rim

I would think that fiting c5 or even c4 brakes into the 17" wheel with AFX spindle will be a problem. Tobin at Kore3 would be a good person to ask.

6" Bs should not be a problem.
I have 18"s w/ 5" BS and would like that extra fender clearence.

Tad - I have that combo, and wish I had 6" of BS - I only have 5.5, and the C5 calipers didn't clear the spokes of my Smoothies. I ended up with a 3/4" adapter, which made the 5.5 not enough.....

I run that combo with a 15" wheel, you shouldn't have any issues, the SSBC brake kit I run barely fits, but on a 17" wheel you'd have tons of room.

Could be worse.
Wanna trade rims?

You'd have the same problems that I did with them.....You couldn't run the vette brakes without the adapter. I ordered two new wheels for the front...

I run 17x8s in front with 4-3/4 BS. I have an 1/8-inch spacer to clear the Baer 6S calipers on 13.5-inch rotors.

It's real tight, but it does clear. Looks bad ass too!

Check my pics to see how it looks.

Most of our A body AFX clients run 17x8 or 8.5" wheels with 5" BS. 18" or 19" same thing. You could go a little more to 5.5" if you like but some aftermarket swaybars may rub the tires at full lock. Caliper face to wheels spoke clearance is a function of the wheel`s joe distance (wheel mounting surface to rear of spokes) not the backspacing. A wheel with too little caliper clearance will remain so no matter what it`s backspacing is. The C5 type brake setup is so common these days you can just ask most wheel manufacturers if their wheels will clear them or not. Usually only old school style wheels may have a problem. Mark SC&C

Tad, the original intent of this post was to find the clearance between the wheel and the upper ball joint/contro arm with the 6" BS...

I still plan on 17", 6.0" BS, SC&C upper arms and C5 brakes... The spindle choice will be decided by wheel to upper arm clearance...
