Hey Crew,

 

Install vehicle 1972 4 door 510

 

I recently purchased from Technotoy a Wilwood big brake kit, ZX front coilovers (plus camber plates), Lower control arms, adjustable tc rods and added a used set of Zhubs.

 

After installation we had to put in a 1/2" spacer to clear the caliper and longer studs.

 

Main issue is now my 15x6 swastika Z rims dont clear the fender well.

 

Has anyone got any good ideas or experience with this style of set up? Technotoy wasnt very helpful although it was kind of late of Friday when they got called......

You could adjust the control arms to be 1/2" shorter if you are set on those wheels

He didn't say the control arms were adjustable only the tension rods. It's probably that 1/2" spacer causing the problem.

Probably better for me to move this there, rather than having a double post.

In my experience, Gabe is extremely helpful. Try sending him a detailed email about your issue. You could always buy a set of their gtx2 adjustable control arms as well, available in custom lengths at no extra charge.
Chrome door handles are under rated.

If you shorten the control arm, you've also got to adjust the camber. Do you have a 1/2 inch of camber adjustment up top?

 

Try a different wheel. Custom wheels are expensive so you may also consider modifying the wheel. I've chucked them up on a lathe and back-cut the wheel for caliper clearance. Depending on where the caliper is actually hitting, this may not be a bad idea.

Grind the caliper for clearance?

If they're 12.2" rotors, then you probably need 16" wheels .. there's only a few 15" wheels that fit over that size brakes

Too late to research first.

Gonna need some different rims or back cut the swastikas. If you shorten the lca you may have to mod your tie rods.

Thanks for the suggestions.

Bit of a bummer as the technotoy ad stated that 15" rims would be fine or I may have just got the 510 coilovers and 2 piston calipers.

I wanted the best as I am hoping to do an engine swap to an Sr or Ka over winter and stopping is obviously most important.....

Going to look first at LCA length and maybe get the different model if it is a bit shorter. Call Techno back today.

Hate to grind back the caliper but maybe look at that.

16" pos offset rims seem the possible answer too.

Decisions, decisions.....

probably only a few very specific 15 inch rims fit over those. circle track type steelies may be one of them.

 

that's a fuck ton of brake for a 510, your gonna do front flips when you hit the brakes lol.

 

stock zx brakes would probably been enough for ya. unless your planning on 500+ hp.

 

rear discs too?

Stock zx would fit and they will stop a 500 pound heavier car. I mean your braking is limited by the tires traction, just how much caliper and rotor diameter do you really need?

single piston rear brakes from silvermine went on without a problem. added a brake proportioning valve also and 15/16 master.

Not planning on 500 hp but will have a turbo on a ka24 so about half that in hp depending on tune.

realistically the price was consistent on most of the stuff so for a hundred or so more I thought may as well get the big set, Technotoy stated 15" rims would fit the kit so it seemed the obvious choice as I was already running 15s with good tires.

In retrospect I definitely see your point, I could have saved a hundred bucks or more and had a simple install while still having ample stopping power.

At this point I may just pull the brakes and get a smaller set and sell the 4 piston as used in the classified. If the stopping power is over the top even with the higher hp and heavier motor as well as having to change rims to high offset seems like it may be more cost effective to start over as well as more practical for stopping power.

 

Live and learn.

Bummer on the misfire there. I have Troy Ermish's smaller rotor Willwood brakes on my SR swapped 510, and they have ridiculous stopping power.

Thanks for All your guys support and assistance

 

Pics to follow as its dark as heck here and pissing rain

 

So......

 

After many adjustments put to max and/or min on the control arm and tc rods.

a 1/4" hub spacer on each rim

about 5 deg neg front camber  (more to learn in this area this came from the alignment shop)

a trim around the ball joint on the control arm

a trim around the rear fender metal of about 1/4"

multiple long distance calls to Technotoy (they were pretty helpful in the end)

Bump steer spacers which arrived very late to the party

Wheel alignment

Lots of hurt feelings , knuckles and whatnot , Extreme gratitude to Tyson and Doug

Multiple break proportion and ride height adjustments

 

 

We are rolling with a decent lowered 510

Pics to Follow 

 

Thanks Again All

For anyone ordering the big break kit with the ZX coilovers

Call Technotoy and talk to the guys there.

The tubular control arms are better suited to this application and give more room for adjustments

They have some other tips and stuff also

 

Or just save the trouble and use 510 stuff they have for a 10% savings in material cost and few dozen bottles of aspirin for the headaches you may get if you take the harder road.

just sayin....

I like the adjustable ball joint t3 has but the futofab lowers are great and use the stock ball joint and will last forever
