I’m more than happy with my brakes, however I’m tempted to fit the bigger 1.8 discs, a question for those who have done this mod, is it worth it? Is there a dramatic improvement?

I think it depends on your driving habits - tracks vs road, fast&furious vs Class 1 Police style - and also your engine power. Standardish power seems to be fine on most brake setups, even the 1.6, but moar powaaaa turbo setups on track probably do need the 1.8 setup, I reckon. I think I recall reading the mk2.5 setup is overkill for all but crazy power setups?? I'm not sure this post is any help  lol |

I have the 1.8 kit on my 1.6... I haven't noticed much of a difference tbh

What wannabe said. Depending on the definition of crazy power.
The faster you go on track, the more brake you will want. Lightness reduce the need for big brakes.

I went from a standard mk2.5 big 1.8 (143bhp) to the 1.6 setup on my turbo car.. (moar) - the loss of 'STRONK BRAKING FEEL' was enough to make me go out and get a BBK.
the mk2.5 setup seemed to give a lot of confidence to me, more than I could get with the 1.6. That said the 1.6 setup is used by racers, where pad choice is probably more important, and so on..

That said the 1.6 setup is used by racers, where pad choice is probably more important, and so on.. is that race class rules? or, to reduce the unsprung wieght (larger discs, calipers etc.) & flywheel inertia (larger diameter disc)  when racing (& rallying) the idea is to go fast, by definition a big-brake-kit is the opposite of whats wanted to go fast  ^^ my thoughts on rallying, also try to get round the corners & course as fast as possible, obviously without using too much 'scenery' for assistance   anyway, larger diameter discs are same as a longer spanner, more 'mecanical-advantage', also have more surface area so hold less heat over time? disc material / vent type & shape / cooling air ducting also contribute to effectiveness, brakefluid & pad material are another story anyone changed fluid recently? a good & cheap 'upgrade'  Rich. |

I suspect with race pads, getting the disks warm, the 1.6 setup works well really.
The mk2.5 setup is more closely like a modern OEM braking 1500KG car setup, yuge brakes under yuge wheels, streety great-from-cold pads.

Quality parts rather than cheap parts will make more difference than 1.6 vs 1.8. People complain about their 1.6 brakes, but most of the time the problem is sticky calipers, cheap pattern part discs and probably a set of ebc pads, which are really not suited to an MX5

I currently run greenstuff pads front an rear, I find them more than adequate when used aggressively, I just want to know if a set of 1.8 discs with larger diameter are worth fitting?
If there is no “wow that’s Canoeing brilliant “ when I hit the brakes then I won’t bother

I think mine were about 15 quid from autolink I'm interested in this too. I have some from Autolink sat on the shelf, including a set of rears I think, that are coated to allegedly cut down on the surface rust. My trusted local garage suggested not fitting anything other that quality discs. No track use (yet) so just getting to and from Autosolos lately, and parked outside for long periods, hence very sad looking rusty discs  |

I think mine were about 15 quid from autolink I'd say getting good discs and pads will make twice the difference going from 1.6 to 1.8 pads. I can't honestly tell the difference between 1.6 and 1.8 brakes in most normal driving conditions, I could tell the difference when I returned my calipers and fitted good discs and pads. On track, the difference is amplified. Overall, I'd rather save the weight and have good 1.6 brakes Personal opinion - EBC aren't bad, they just aren't good either. Like Toyo T1r tyres, they are fine, and cheap, and you're happy with them until you try something that's actually good. Then you feel like an idiot for not changing sooner! Russell |

Russell lol at the EBC/Toyo comment So true! (IMHO!) I guess the next question is 'which discs are good?'. OEM are surely crazy money, so are we just talking about, say, Tarox- / Brembo-branded pattern parts from ECP or GSF? Or going for some super-duper slotted/drilled things from manufacturers of OEM parts for supercars etc.? (none of which I can recall right now because apparently my brain has dumped all non-essential information out of itself recently!!) |

So , general consensus appears to be that 1.6 callipers and discs (in excellent condition, that mine are) are more than adequate, it’s the pads that make the difference.
That makes sense because it is the pad that grips the disc!
I knew that already, so perhaps my question should have been what are the best pads for fast road use?
Which pads will make me say “Canoe me those green stuff were prarrie canoe”?

It really depends what you want to achieve. I found the SVT brakes were considerably better than the standard 1.8 brakes that came on the car - so apparently an inch does make a difference! If you're considering the move to aftermarket discs and callipers there are extra benefits... Weights for just the brake combinations: Stock 9 1/4" (91) front calipers, rotors, and hardware = 15.5 pounds NB 2002 sport OEM disc (part worn) 10.7lb, OEM front caliper with pads (part worn) 10.18lb = 20.88 pounds 11" corado rotor, wilwood caliper and hardware = 19.2 pounds 11" custom rotor, wilwood caliper and hardware = 14.6 pounds DBA 2 part rotors, new 9.27lb, Wilwood Dynalite calipers and pads 4.42lb = 13.69 pounds Combine the weight savings on the brake components with a decent wheel and you can save a shedload of unsprung weight. Info ripped from this page.
If I was on a budget, I'd throw a decent pad in your 1.6 callipers and spend my money on lighter wheels. |
