Well sorry about the title.

What I am after is the PCD, spacing, & offset from the rotor centreline(in plan view) for the two bolts that hold the stock caliper onto the hub, or in the case of an aftermarket caliper hold the mounting bracket to the hub.

The two are shown in this photo (Pinched from this very forum) just in front of the drive shaft.

as far as the bracket goes it all depends what dics/had combo your using

Thanks for the info.

What I was chasing were the locations of the bolts on the other end, ie as they bolt up to the hub. The outside biut is ok as most manufacturers publish this data, but the Nissan end of it I don't have any info on & don't believe I can measure it up accurately enough.

well its 100mm spacing. and ofstet is usualy centerd around using a rotor with a 15mm hat height. most calipers that are radial mount have around a 50 mm ofset. its really a case of having your disc and caliper sitting on the disc with new pads and getting out the ruler

Hooray, I'm helping! (that's my photo). I have nothing useful to say I think, but I think it's funny because I was just browsing around and had to do a double take at the photo! Oh and I wanted to say thanks to T04GTR because your data helps with the project I'm currently doing. Namely, buying and fitting replacement discs and pads for my non-standard setup, which shouldn't be a project but it is!

      Hypergear Turbochargers and High flow Services Development thread

      Here's one I help build and tuned a decade ago, Garrett  GTX3071R Gen 1, T3 twin scroll 0.83 rear housing. Went from larger 272 cams down to smaller Tomei Poncams to help with the low end. S13 non VCT motor. Car was purpose built for the track, hence low down was the focus. Note the actual dyno chart shows lower boost, however the EBC and boost gauge showed 1.9Bar (Ignore the torque, I was young and didn't know how to set derived torque)

      I’m doing some side developments on SR20det S13 engines, its one my hobby cars used it to compare flow capacity of some smaller size wheels. SR20det is one of another JDM legendary engines I'm sure there are plenty of SR enthusiasts on this forum, I will share results some common turbo configurations here. a quick run down of what the car is: Wide body 180sx Type X with black top engine (blue). It has: Stock bottom end Haltech 1500 ECU 5-0 motorsports trigger kit Kelford SR20DET Beehive Spring with Titanium Retainers Kelford Cams SR20DET S13 188-B 268/272 Cams G25-660 Turbocharger in T2 .64 rear housing internally gated ARP Head studs MLS head gasket 1000CC ID injectors Walbro 450L Fuel pump Front mount cooler kit JJR’s 3 inches turbo back exhaust (its too short for the 180sx it had to be extended) Pump 98 fuel Hub Dyno tune So far made 270rwkws at 22psi full boost by 4500RPM. Engine is very knock limited hence a pretty bad looking top end. From previous experiences it seems like SR20dets are happier with bigger size turbine, some thing like a GT30 would make way better top end, but on same time response is lost. It won't be a problem with S15 VCT engines. I'll be testing alternative turbine housing, turbine wheel and possibly dump pipe options for extra flow to resolve the problem and of course E85 would resolve all the issues.

      Awesome writeup and details. Thanks for sharing the story so far. I can relate to parts of it with my previous car and some of the issues I had to deal with.

      Wow the colour matched hard top completely transforms the car. Are there any nice front lip options for the car or is that off the table?

      Generally yes but for some reason I've been ruthless this time around!  I might even need to do another tip run after the way I've finally been able to hit the delete button on shit I've stepped over, stepped around and tripped over for the past 10 years!
