V-Sport AP ARacing 296mm 4 Piston NA/NB Front Brake Setup

[Luke]

Update.
New alternatives.
I don't know how I never found this mob in the UK as they have been doing kits for a few years now.

FreakyParts

Several kits available.
I excluded the kit that uses Wilwood Powerlites on front NB8B rotors and the Powerlite rear kit also on NB8B rotors.

298x32mm discs Option of 309x32mm (Pretty sure these are the 11.75x1.25 Wilwood rotors, which makes other brands available like AP, PFC, HAWK)
Hats, lines, brackets and and a set of road pads.
£1,190.83

Mazda MX5 (NA/NB) Brembo 4 pot big brake kit

Mazda MX5 Mk1/2 (NA/NB) Wilwood 4 pot Midilite Brake Kit
Wilwood Midilite 4 pot Calipers (Not sure what these are as WIlwood does not call any caliper midilite)
300x24mm discs, 1 piece (not sure what Euro car he is stealing these from as they are 4x108 with 4x100 as well)
Lines, brackets and and a set of road pads.
£649.17

Mazda MX5 Mk1/Mk2 (NA/NB) Wilwood Dynalite 4 pot brake kit
Wilwood Dynalite 4 pot calipers
280mmx22mm discs, 1 piece (VW Corado discs) Also available in 2 piece
Lines, brackets and and a set of road pads.

The best thing is Stewart will sell just the parts you want unlike alot of other sellers.

I have asked about the kit with the Brembo/Renault callipers and shipping was not as bad as I though it would be.
£160 for the whole kit
£65 without the discs and pads. (can get these easily in AUS, will just have to re-drill the rotors which is what he does anyway)
As I know which disc it uses, I also know it will increase the front offset by 0.8mm.
Rotor is DBA573 / Brembo 09-9368-10
Brembo has very good tech drawings so shows you every possible dimension.



The top Wilwood Superlite kit is an option the Americans should be selling!!!
949/Super Miata actually has a kit under development using those rotors with a 4 piston superlite caliper.
I believe track speed did as as well before they stopped selling stuff.
Some of the guys in the US have been making their own home made kits using the 1.25 inch rotor as well.

The biggest issues are Space between the rotor and lower ball joints as well as rim s that fit.


The big difference between us and the USA has to be piston area.
Most people in the US are replacing NA6/NA8/NB8A Callipers which were also fitted on their NB8B's up until 2003.
That piston diameter is 2 inches. Area of 3.14 Square inches.
Our Aussie NB8B's have 2.125 inch pistons. Arear of 3.54 Square inches.

I note that alot of the more track oriented kits the US suppliers supply with Wilwood calipers have Dynapro 4 or 6 piston with an area of 3.0/3.08 square inches. This matches their OEM pistons size quite well but is not really the best for our NB8B's.
Wilwood does not really make caliper around 3.5 square inches. They seem to go from 3 to 4.
So it really seems to be a choice of either hard pedal or long pedal on our NB8B's unless you stuff around with the master cylinder as well.

I contacted V-sport last week about the kit, and they advised that they no longer sell it. They asked for my budget and suggested they could put something together for me, using a different calliper. I haven’t circled back to them yet.

Thanks Luke for the additional options information.

EOI:

If the AP Racing kit could be brought back through a group buy, would you be interested?

I don’t have pricing as yet, but expecting it to be about $3000 for a front set of brackets, hats, calipers, lines and rotors.

I solved my problem.
I payed $14000 to upgrade my brakes.
Sold 1xSE and bought 1xGR Yaris to have 356x28mm 2 piece rotors with bespoke 4 piston caliper's.
Would not recommend doing your brake upgrade like this.
BTW, the MX-5 is still the far better drive. Good thing I still have the NC which drives better than the NB. Awaiting the burn.

Hehe!
I will get an NC one day. Maybe as a dirt car.
