T3 vs K-Sport vs FC brake conversions Opinions/Help needed

[OMR510]

Looking in to doing a big brake upgrade for my AE86 and have been looking at the folling 3 brake upgrades.

Firstly the T3 Wilwood Big brake kit

The K Sport 11" ProComp big brake system

and lastly the AJPS FC RX7 Brake upgrade

I am looking for people who have bought these kits and fitted them , any problems they may have had as well as braking performance ,pedal feel , fade etc etc

Price cost vs overall quality etc

I have 15" rims so I am not looking for a smaller kit, I dont want to change to XT130 Struts to do the Hilux/Pug conversion, I am not converting to coilovers as it is impractical where I live due to the really average roads out here.I am a mechanic so I have no problems with doing the work myself and I really want a no fuss brake upgrade to install.

Price wise the best deal right now seems to be the T3 kit at about $900AU to my door.

Sensible, informed opinions and suggestions would be appreciated

K sport= POS there just for show, rx7 could be the cheapest if u bought everything second hand but bit of a dick around to find all the parts and rebuild the calipers, wilwood would be easy as they come with everything just have to bolt it all together, i think u can tell them to change or leave out the disks as there cross drilled, they might not crack with ae86s being so light but cross drilling looks gay. With all of these i think u would need a bnr32 brake booster as well as upgrade the rears to balance it out a bit ,r31 diff or u can get these plates that u can bolt a twin caliper set up and think they use skyline disks and calipers i think. Never ownd any of these nor felt the need to up grade the brakes these are just my observations

Ill display my literacy here.

I vote TTT wilwood kit as the best.

Its lightweight, unlike the other options, has high quality bauer rotors from Germany in my kit, brand new forged alloy calipers, cnc dog bones, braided lines, decent pads with the kit too, you absolutely cannot go wrong. Been using it for 3 years + still on original pads and rotors, and they are barely worn.

RX7 kit works fine but there are 3 different rotor options depending on rim diameter and what brackets you can source, plus you couldn't buy the parts and rebuild the calipers for less than the wilwood kit costs to your door. Cross drilled and slotted rotors are fine as long as the cross drilling and slotting is done at the right time in the mfg process, prior to the heat treating. Cheap shit is always going to fail. Plus the RX 7 'carry-pers' will stick past your wheel mounting face and cause you issues with finding suitable wheels. You have a similar issue with the wilwoods but its several mm less protrusion so worst case scenario is 3mm spacers to fit 99% of wheels.

K sport isn't even a blip on the radar of as serious kit, cheap shit with poor poor mettalurgy like most ebay china crap and its not worth your life or mine really since we are talking about brakes here!

Some people will try to tell you the wilwood calipers cannot be approved by an engineer for road use but this is a commonly bandied about piece of misinformation. Something to do with secondary dust seals. Maybe 20 years ago but cars come out brand new with the same caliper and piston design and that passes adrs so its a non issue, maybe just an issue for a stubborn old idiot that wont accept that times have changed and technology has advanced. lol. Anyhow, people who have a different brake package will be jealous and find themselves saying things like, "they dont have dust seals so they cannot be approved for road use so your wasting your time and money". That's just something they say to feel good about having shit std brakes. bahaha. New Holdens and Fords come out with AP racing calipers on the high end performance models and they are made much the same as these are.

i run fc's with civic discs and ajps adaptors on my notch they work great, was the most cost effective and fit nicely under my 15/8 meisters the only thing with them is without a nrca they run really close to the lca

as for willwoods the pad life isn't great (from experience) when they get half worn the piston can cock off on a angle this was a few years ago and on a race car

thants my two cents

Another option in case you weren't aware. I may use this kit, fits 15" rims.

I know of someone who is using it and can not fault it, very easy fit, local support and parts. Any option you choose im pretty sure you'll need a bigger master cylinder and need to FIDDLE with brake lines.

Haha told! My 2c; I can safely say that Matt's car pulls up very, very well.

[sundee]

any FYI you do not need to change the master to run the T3 wilwood BBK. AND you wont have a problem with the X drilled rotors.

If I didn't have bigger brakes I probably would have gone for the wilwood kit.
Instead my car has MR2 SW20 calipers up front with redrilled 281mm rear rotors from a MR2 SW20. The calipers bolt straight onto the standard struts with help from some custom cnc made brackets and I run 15" rims as well. I still have 2 sets of these brackets for sale, check my for sale topic. Let me know if you're interested it might be a cheaper option for you.

how about the cresida caliper with an xt130 strut option?

also running a coilover doesn't always mean a firm ride. I run a 4.9kg/mm that works really well and isn't uncomfortable.
