When you say "better fit" do you mean bigger? What are the diameters of the  M/C s? Does the Z33 have the right pipe connections in the right place? Is the 33 booster bigger? If everything checks out you should be fine. If the 33 stuff is not bigger there's really no point. Or just put the brakes on first (assuming that you have checked that they will fit) and worry about the M/C etc if you think you need to once you have tried the brakes.

If its the 350z brembo calipers they are the same as the R32/33/34 GTR ones just the rear mounting tabs and bolts are different. A BM50/57 will be what you want, the 350z BMC outlets are different but same bore from a quick google search.

Thanks for the input I meant I thought it would give a better brake bias but if the bore is the same (Could have checked that good point ?‍♂️) there won't be any real benefit. 

The calipers have the same mounting dimensions you just need to drill the holes out to a 14mm.

Bias is actually a separate thing. Beyond just the simple brake size differences front to rear (rotors and pistons) the MC itself has an internal bias valve. There is a currently active thread on the BM57 that you should read. Not all MCs of the same type (ie, marked BM57) even have the same characteristics. The Z33 MC could be just about anything. Better than other options, worse than other options, same as other options.

      Duncan's V37.......race car?

      Something I meant to say when we were chatting the other night about having an open trailer floor being great to work on a car, but you've never used the feature... It's a great place to park a car after doing suspension component changes, and do the tightening of all the bushes with the car sitting at full ride height. Especially when you don't have a 4 post hoist!

      That is way more science than even I would use. I just eyeball it, not even accounting for the non-verticality of the tape measure when held on the lip and the centre at the same time. +/- 2mm is good enough for the girls I go out with.

      So, before putting them in I need to understand the stock ride height. This is how I measured it: First, check the diameter of the wheel's centre cap, it was 52mm. Then put a piece of masking tape approximately across the centre and measure 27mm (half) from at least 3 sides to get a reasonable idea of the centre of the wheel cap. Mark that with a horizontal line as one measuring point. Then, directly above the wheel on the guard, put another piece of masking tape in approximately the centre. Use a string line to find out the point on the guard above the centre of the wheel cap and mark that. Then it is simple, just a tape measure to check the distance from centre of the wheel to the centre of the guard. Final results where  LF: 381mm RF: 379mm LR: 401mm RR: 400mm Pretty even considering they are 120,000klm old factory springs, lets call that 380 front and 400 rear.

      So....knowing that I have a problem with power steering temps on track and another Wakefield day booked in next Friday, I've done the obvious thing They are very reasonably priced at $1650, considering they are a big monotube shock, double height adjustable (don't have to change pre-load to change ride height), one way adjustable damping and standard sized and customisable springs if you want something other than what comes with them. They come with 9kg/mm front and 4.5kg/mm front and I went with that as a starting point because I'll add adjustable sway bars too https://justjap.com/products/bc-racing-coilover-kit-ds-ds-infiniti-q50-v37-14-current#description Unfortunately they didn't come with rear strut tops so I've re-used the factory ones which was a bit of a pain. Also, the adjuster for the rear shock will be an absolute nightmare to get at, and while there are extensions in the kit I can't see any way you can actually attach or use them

      One Headlight isn't working - Driver Side Fuse Keeps blowing

      By Duncan · Posted

      I also had 2 bulbs blow at once, years ago in the stagea. made for a fun drive home. The issue was the voltage regulator had failed in the alternator and it was giving 15+ volts. Really, I was lucky all that was fried were the headlight bulbs. So, I'd suggest you check the voltage across your battery terminals with the car running and warmed up. Yes, you will need a multimeter to do so, sorry.
