You have options to purchase either the .625", .70" or .750" sized Wilwood master cylinders. For cars with a single piston rear caliper, .70" or .750" is best. For cars with Brembo/Akebono calipers, the .625" or .70" is best.
The .625" will have the softest handle pull but you will have a longer handle "throw" before the rear brakes lock up. The .750" master will have the shortest throw but require more handle force to lock the rear brakes and can be overly stiff. 

Our recommendation is the .70" master for a nice middle ground that typically works well for most setups.  For G35s, we suggest using the  .70" or .750" to minimize handle pull so that less of the shifter bezel needs to be trimmed, regardless of what calipers you use.

Bench bleeding your master before installation is highly recommended and will greatly aid with bleeding your fluid system. 

Our Dual Caliper kit is made to work with the oem caliper options and it comes with hardware for both Brembo and non-Brembo calipers. However, you can not mix and match calipers. Meaning if you have Brembo calipers for your normal brakes, you must use Brembo calipers for your second set. If they're non-Brembo calipers then you must also match the year you have. 03-05 year calipers and rotors are different size to 06+ and will not fit together.

Any "Full Size" 1911 grips will directly bolt on. When you search for 1911 grips online, the retailer will specify either Full Size or Compact. Compact screw holes are too close together and won't fit.

Unfortunately no. The transmission tunnel is shaped differently on the automatic cars and the shift boot bolt holes are different. Our hydro bracket will only directly fit factory manual cars, no automatics or auto to manual converted cars.

The rest of the hydro kit parts will work: Dual Caliper or Inline. So consider using our universal Low-Pro Reverse Hydro. If you'd like to purchase one of our complete kits but swap out the hydro, contact us and we can give you the same price.

The dual caliper brackets "stretch" the axles by 7mm by spacing the hub away from the knuckle. Although axle spacers aren't required to do the install, its certainly good insurance for your axles.

Our general recommendation is to use the 7mm Axle Spacers to take up the space created by the dual caliper brackets.

When you lower your car or add camber, you also stretch the axles in a similar way which can cause them to seperate and break at the CV joints. 10mm spacers work for most guys with moderately lowered cars (or very soft suspension) but have conservative camber settings (less than -3 degrees). 14mm spacers might be necessary if you're very low and/or run aggressive camber.

If you've converted your car to use 370z/G37 axles - you can use our 370z Axle Spacers but only the 7mm thickness. The 12mm version is too thick for this combination and will cause your axles to bind and break.
