Default 960=850!

Right front of the ol' 960 right? New brake rotors right?





But no! I was doing the CV joint on my sister's 850 ( ), and had the brake hardware off, and figured, what the hell, right? So ya, right there is an 850 rotor (which as far as I can tell, is identical to the 960 rotor) on the 960 spindle with the 850 brake mount (which mounts the 850 caliper). In other words, any 850 BBKs will bolt right onto a 960. Woo!

Sweeeeeeeet.

Gotta love it when there are (relatively) a lot of new options all of a sudden...

Only takes about 2 bucks worth of washers to make the 850 brakes bolt up to a 740 too.

Them thar is a pair of 302mm rotors (yes, I know they are rusty!)




Do the 960s have the FWD offset for the wheels?

ok i've been sayign this for liek 2 years now. s90 and 95+ 960 use 850 rotors. and 940 jumbo calipers and yes they use the 940 jumbo caliper brake mount. i had s90/960 front knuckles and struts in my 940 so iknow from experience! and yes all 95 + 960/90 series are frotn wheel drive offset rear wheel drive cars!

what happens is since the 940 control arm is shorter you throw off camber. know what rack does teh 960 use. if we have control arms make up to correct ti and the 960 uses teh late 940 koyo rack we may be able to use teh 960 innter and outer tie rods and custom control arms to bolt everythign up peachy keen.

I thought this was common knowledge... late 960 uses the same rotors as the 850 and have FWD offset = huge backspacing.

Can you elaborate on your setup? Did you use the washers to back space the rotors or for the calipers? Did all 850s use 302mm rotors? Any more pics?
thanks

The pics all turned out crappy. The washers were used to space the bracket further outboard. IIRC none of the 850s came with the 302 kit. Some of the *70 did though.

302s w/o spacers:


For the spacers I ended up just buying pairs of various large washers at ACE and tried mixing/matching til I got the bracket centered on the rotor.

I have a slightly used set of Brembo calipers, brackets, lines, and 2 piece rotors for a 850 at my work. I could probably give them away for cost +10%.

I assume the S70 calipers & rotors work for this swap also. Is it worth doing with the 280mm rotors & caliper brackets, or should I hold out for a set of 302's?

You have a bigger piston with the s70 system, but it's just one piston instead of the 2 on the 740. The 280mm rotors are just a hair bigger - my 280 bracket wouldn't quite bolt up, but it was REALLY close.

It would be ok if you already had the parts - and it would make a 302mm swap that much easier later on.

And those were with ****ty ass pads. The Porsches outstopped them "stock for stock" in terms of pads. The next set I try should be ALOT more fun

Glad you finally just took my advice and raided the hardware store! So what did it end up being? About a 1/4"?

Slightly less really. Want me to send you a set? Maybe you can offer proper spacers - or do you think the washers will do the job safely?

You can get actual "spacers" from mcmaster for just a bit more. I'm using some to space out my timing belt tensioner--its good for some really accurate spacing

Are the S/V 70 T5's more likely to have the 302mm brakes? Or is it just a random thing? I have a 90 740 turbo, am I better off with the 940 "jumbo" brakes or the S70 302mm?

from the ebc catalogue you can get the disc heights, basically how far from the outer face of the hub section to the back of the disc.

i think jumbo 940's are 56mm, 850/960 (94+) are 51mm with the 302's being 50mm which is why you need to space the caliper bracket out 6mm for the 302's

do wonder about S80 brackets, are they same bolt spacing as those had 305's which are 51mm tall so would need 5mm of washers.

Does the 302mm rotor and caliper fit in a 15" wheel?

i think that might unlikely seen as volvo colombo wheel doesn't fit. but it is only 11.89" so would depend on the inner layout of the wheel.

Hmm, wonder if I can get S80 brakes inside my 17" C70 wheels on my 945?
