Ok Here Goes.

I am currently coming to the pointy end of my brake upgrade. But as luck would have it, i need to finalise some details, and my car is not currently at home, so it makes this just a little harder than usual.

I need to know the factory sumitomo caliper bolt specs for an R32 GTR, size, pitch, and length for both front and rear.

After hours of searching the interwebz, and sifting through a whole heap of useless shit, this is what I have come up with.

Front:

Size M12

Pitch 1.25

Length ???

Rear:

Size M10 ???? (I have read both M12 and M10, so I need to confirm)

Pitch 1.25 ???

Length ???

Also can someone tell me what the caliper flange thickness is on both the front and rear sumitomo calipers??

Once I can confirm these details, my caliper brackets can be made and I shall enjoy copious amounts of braking power.

Any help would be appreciated.

Cheers

Damo.

Pitch is 1.25 front and rear.

Bolts on an R34 are a size bigger than the 32's so may be adding to your confusion. I dont remember them as 10mm - thought they were 12 as per the fronts.

As for length - get a machine bolt ie one threaded all the way along its length and cut it to suit. You probably wont get the exact length you need anyway.

You havent mentioned grade either - 4.6 or 8.8?

Cant help you with the thickness of the flanges, sorry.

Well the whole point of this is, I would like to use the original factory bolts and get the brackets made to suit. Hence the reason i need this info to be 100%.

But I cant get them off of my car as it is in a workshop about an hour and a half away from home.

As for the length, i wanted to know that for the thickness of bracket, same reason for the flange thickness.

I dont need to buy another set of bolts, I just need the specs.

I have a set on my car and want to use those, but i dont have access to them to get the specs to give to the guy designing my caliper brackets, who by the way is on the other side of Australia, so I cant just give him the bolt.

Already thought of that and asked, they take their sweet ass time with everything, and thought this avenue would be faster, as the guy designing the brackets is going on a few weeks holiday as of tomorrow. So need to get the specs to him by this arvo or I'll be put back a few weeks.

Time is of the essence lol.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      The engine stuff is Greg Autism to the Max. I contacted Tony Mamo previously from AFR who went off to make his own company to further refine AFR heads. He is a wizard in US LS world. Pretty much the best person on earth who will sell you things he's done weird wizard magic to. The cam spec is not too different. I have a 232/234 .600/603 lift, 114LSA cam currently. The new one is 227/233 .638 .634. The 1.8 ratio roller rockers will effectively push this cam into the ~.670 range. These also get Mamo'ified to be drilled out and tapped to use a 10mm bolt over an 8mm for better stability. This is what lead to the cam being specced. The plan is to run it to 6800. (6600 currently). The Johnson lifters are to maintain proper lift at heavy use which is something the LS7's supposedly fail at and lose a bit of pressure, robbing you of lift at higher RPM. Hollow stem valves for better, well everything, Valve train control. I dunno. Hollow is better. The valves are also not on a standard valve angle. Compression ratio is going from 10.6 to 11.3. The cam is smaller, but also not really... The cam was specced when I generated a chart where I counted the frames of a lap video I had and noted how much of the time in % I spent at what RPM while on track at Sandown. The current cam/heads are a bit mismatched, the standard LS1 heads are the restriction to power, which is why everyone CNC's them to get a pretty solid improvement. Most of the difference between LS1->LS2->LS3 is really just better stock heads. The current cam is falling over about 600rpm earlier than it 'should' given the rest of my current setup. CNC'ing heads closes the gap with regards to heads. Aftermarket heads eliminate the gap and go further. The MMS heads go even further than that, and the heads I have in the box could quite easily be bolted to a 7.0 427ci or 454 and not be any restriction at all. Tony Mamo previously worked with AFR, designed new heads from scratch then eventually founded his own business. There he takes the AFR items and performs further wizardry, CNC'ing them and then manually porting the result. He also ports the FAST102 composite manifold: Before and after There's also an improved racing crank scraper and windage tray. Helps to keep oil in the pan. Supposedly gains 2% power. Tony also ports Melling oil pumps, so you get more oil pressure down low at idle, and the same as what you want up top thanks to a suitable relief spring. There's also the timing chain kit with a Torrington bearing to make sure the cam doesn't have any thrust. Yes I'll post a before and after when it all eventually goes together. It'll probably make 2kw more than a setup that would be $15,000 cheaper :p

      Because the cars wheels are on blocks, you slide under the car.   Pretty much all the bolts you touched should have been put in, but not fully torque up.   Back them off a turn or two, and then tighten them up from under the car with the wheels sitting on the blocks holding car up in the air.

      Yes. Imagine you have the car on the ground, and you mine away all the ground under and around it, except for the area directly under each individual wheel. That's exactly how it'd look, except the ground will be what ever you make the bit under each wheel from

      Yes, if you set the "height" right so that it's basically where it would be when sitting on the wheel. It's actually exactly how I tighten bolts that need to be done that way. However....urethane bushes do NOT need to be done that way. The bush slides on both the inner and outer. It's only rubber bushes that are bonded to the outer that need to be clamped to the crush tube in the "home" position. And my car is so full of sphericals now that I have very few that I need to do properly and I sometimes forget and have to go back and fix it afterwards!
