Rear 914-4 calipers with a spacer?

Post by crankwalk » Sun Feb 10, 2013 12:56 pm

Hey 914 folks a quick question for you,

I have a Dino 308 GT4 that uses the same ATE calipers as a 914-6 which are a FORTUNE as you all know. My question is can you take 914-4 calipers (I have a set) and get a spacer and longer bolts for them from somewhere instead?

Thanks!

Called them up and they said going that route I would lose 15% of my braking surface. I'd rather do that than pay 2k on rear calipers.

Possibly better plan:
Find some "modern" self adjusting calipers.

The 914 rears are not, "venting clearance" must continually be manually adjusted to maintain consistent braking performance.

The Golf/Jetta floating setup works well on a 914 rotor, not sure if room in std 914 location but you are not running a 914.

Passat versions about the same piston area as 914, and have a mechanical parking brake (that must be activated regularly to do the self adjusting part) plus some of these calipers are available in aluminum.

Would need a really good picture of the present setup from top and side to see how your Fubaru is set up//offsets etc.

Ignore all of this if you are running thicker vented rotors out back, in that case look to Ford/GM/Chrysler late models.

Thanks for the reply Piledriver. I have the stock 308 gt4 rear rotors which are 20mm and the factory calipers are just like the 914-6. So basically I need a 3 inch bolt spacing like the 914 ATE calipers have but a 20mm opening for the vented rotors.

I put ATE 320i e21 front calipers on and they fit BUT they are too wide and hit the wheel. Grr

Unfortunately most rear disc setups w/parking brake integrated into the caliper are not vented rotors.

The good news is if you go with a CV mount mini-disc with a mechanical parking brake caliper, your actual caliper choice range just got a whole lot larger.

Not sure if the 2002ti front calipers would work out back, IIRC they are physically smaller than the 320s, but would need spacers/widened.
I can take pics (some are posted in the T3 forum)
(plus they would be kinda overkill balance-wise unless you went with something bigger up front)

Wilwood has the mech calipers ~cheap.

(had this discussion with another lister awhile back, he was on an unsprung weight reduction kick)

All good info. I put 320 calipers on my 2002 as an upgrade back in the day. Maybe even a non Ti 2002 front caliper will fit as long as its narrow and 3 inch spacing on the bolts. I'm not worried about the parking brake being retained at all. I just need stopping and the wheel to fit

Confirm 3" spacing, they are bolt on replacements for early 914 or late T3 fronts.
(still need to run a pair of hoses to it)

I'd still look for something in aluminum, but you are probably way past sitting in the car and going "vroom-vroom" at this point and want "works. now."

:mrgreen: WORKS NOW!!

Exactly. I'm already saving weight by shaving off 4 cylinders!

I'll order one from one of the box parts store and then return it if it doesnt work. They are vented up front though on an 02 correct? It's been a few years. Thanks!

The 2002Ti ones are NOT for vented rotors, but may take a thicker rotor.
The was a version of that caliper that is wider, they can have spacers added.

Since you are 4 cyl lighter dont even worry about the 15% less surface. :D

4 cyl lighter and 30 more hp. Funny how that works!

have you looked into 944 NA brakes, super cheap, very common, and I believe a bolt on affair. You'll have to do your own due diligence to be sure they will fit.
