Bump, someone take the last of these wheels!

I also started my rear big brake conversion this weekend - check out the size comparison of the rotors

Couple of photos from the recent hill climb.

Bump $450 for all 4x DPT's Plenty of people asking about them but no one committing!

Calipers sold

That sucks man! I think ianmack79 jynx'd you with his post above!! Unfortunate to see a clean Skyline take a hit like such, what do plan to do?

Good curve!

I have the Neo engine cover with what should be all the mounting points I think. Shoot me an offer via PM if you like. In fair condition.

Correct, I'm referring to the lead weights used for balancing wheels when you get tires fitted

Pictures of front calipers as requested. They are a bit dirty but paint appears to be good, and as you can see the Intima Pads have heaps left on them. HEL braided lines sold seperately or can bundle for the right price.

What 17's are you running? Here is a pic with some 17x9 Enkei's fitted over the kit - http://alphaomegaracing.com/image/data/productimages/evo350brembo/wing.jpg I'm sure if they are a known brand rim Alpha Omega would probably be able to advise if they will fit over the kit, you may need to be cautious of wheel weights though.

Will post pics after I get home from work for you

Different kits/cars require different bolts - mine uses 14mm bolts I run 18's, I use both stock R34 GTR rims and Concave Concept CC03R in 18x9. I have seen the setup with 17's but you would require a race-style 17's which provide maximum clearance. If I remember next time I'm at the track I will see what I can do

Yep, still have the rotors too at this stage if you wanted to package them.

Thanks I realised that I didn't put a lot of information up regarding the big brake setup, so for those interested, I have written a review and put it in the Suspension/Braking section on the forum. You can find it here - http://www.sau.com.au/forums/topic/459054-review-alpha-omega-racing-350mm-brembo-front-brake-adaptor-kit

Will be very soon

I have forgotten the bolt sizes Scotty, will get back to you as soon as I find out. I wasn't actually aware of an OEM 2 piece for the Evo's but agree with Dale, I don't imagine they would come cheap. Value for money I'm happy with the Attkd 2 piece rotors, and think they compliment the kit well

Nice results, got a pic of the dyno results?

Cheers. Yea the altered bias definitely did not impact on the car in a negative way, was just a noticeable change. I have not fitted a BMC stopper yet as I intended to source one after replacing the BMC and since I had to chuck the stock one back on I haven't bothered as yet. I'm still trying to decide if I want to fit my BM57 sourced from Holford or not, will probably wait until I see how it all feels with the rear Brembo's fitted as well.

Thanks for the feedback guys. Like I said I have had a number of people asking me about the kit so figured I would do a proper review. If anyone wants to know ask me anything feel free to post in here or shoot me a PM

Price and basic mod list with a link to the motorsport/build thread would probably go a long way for anyone interested

I have decided to put together a quick review of my brake upgrade as I’ve received quite a lot of interest and have received many questions regarding them. So here it is, a quick overview of the kit, parts I chose and why, issues I came across when installing, and my final thoughts after getting the car on the track. Company/Product: Alpha Omega Racing / Evo 350mm Brembo front brake adaptor kit Price: $370 plus postage Links: http://www.alphaomegaracing.com http://alphaomegaracing.com/p/50/c/73/Z33/ALPHA-OMEGA/Evo-350mm-Brembo-Brakes-Adapter-Kit-Version-2.html Purpose: The kit allows you to fit front Brembo calipers from an Evo 5-9 (all the same) with Evo X rotors (350mm) to your R32/R33/R34/S13 (5 stud)/S14/S15/Z32/Z33. What’s included: - Pair of CNC machined 7075 billet alloy caliper adaptors - High tensile bolts and washers - Installation instructions (with pictures) What else you need: - Mitsubishi Evo 5/6/7/8/9 Brembo front calipers and brake pads - Mitsubishi Evo X front rotors (350x32mm) - Custom brake lines Alpha Omega Racing is able to provide all of the above parts as well as parts and services (labour) for rebuilding calipers and even fitting if you are not comfortable doing so yourself. I personally opted to source the parts myself but the convenience factor is there of getting everything you need in one spot if preferred. The kit makes use of the Evo X 350mm rotors as opposed to the Evo 5/6/7/8/9 320mm rotors due to a couple of engineering issues, and of course better heat dispersion. Read more regarding the engineering issues on their page here: http://alphaomegaracing.com/i/9/Evo-Brembo-Brakes-On-A-Nissan-Adapter-Designs.html I personally purchased some calipers at a particularly cheap price which I found at the time, along with some Attkd 2 piece rotors. I also fitted these with some new Intima Type D pads. The car sees reasonably frequent track use so going for either RDA or DBA slotted rotors may be better suited for others. I had some custom brake lines made up at a local business which are required due to the Brembo calipers having banjo fittings. I had read in a couple of places that stock Evo lines would fit but it was found that they are too short and would pull on full lock. Test vehicle: 1998 Nissan Skyline R34 GTT – upgraded from stock calipers with DBA4000 T3 slotted rotors Unboxing the kit: The adaptor kit arrived super quickly and was packaged as well as you would expect this kind of part to be. The adaptors are super light being made from billet alloy and appeared to be of very good quality. They have Alpha Omega Racing etched on one side and ‘Made in Australia’ etched on the other. The kit included all bolts required with washers and an instruction booklet. Installation: Install was easy with the only issue I came across being that one of the bolts from the adaptor kit to the hub is slightly interfered with by where the factory brake line bracket is bolted to the hub (I believe this is not on all vehicles that the kit is designed for). The issue is outlined in the instructions provided with the kit, something I would have realised and known about had I looked at them prior to beginning the install (but hey, who ever reads instructions lol). Quick fix with an angle grinder and they bolted straight up with perfect alignment. The bracket is a non-structural component and is purely a mounting point for the stock brake line so there was no issue with removing it. Initial impressions on the street: A quick ‘spirited’ drive of the car after fitment and I found the braking to have more bite, as you would expect with the larger contact area of the pads. The brake pedal had a tiny bit more travel in it due to retaining the stock brake master cylinder. Alpha Omega Racing do recommend upgrading to a BM57 master cylinder, which I did purchase elsewhere but this turned out to be a faulty unit so I refitted the stock unit in order to get the car driving. Impressions on the track: About two weeks after fitment I attended a Wakefield Park track day to test out the new setup. I was definitely impressed and it took some getting used to being able to brake later at the kink/turn 2 especially. On the day I was able to knock 1 second off my previous PB and felt that I was still adapting to how well the brakes could pull the car up. The pedal feel was softer then before but not bad, it had more travel which some would prefer. My next attendance at the track saw me cut another 0.7 seconds off my PB, meaning I had cut almost 2 seconds off my times previous to the brake upgrade. By this point I had gone from braking between the end of the wall and the kink with the stock setup to now braking after the kink. Overall opinion: The quality of the adaptor kit is top notch and the customer service provided by Wing at Alpha Omega Racing was great. The install/fitment was perfect and the only thing that could have improved on this would be for me to read the provided instructions as I already mentioned. The flexibility to purchase the other parts is great as it allows for the money conscience buyer to source their parts or use already owned parts, or for the track conscious people out there to upgrade the setup even more. For the time conscious person, everything can be purchased from Alpha Omega Racing making it a quick process to get everything needed. The upgrade over the standard setup is definitely noticeable in terms of braking ability and the larger discs help with heat distribution too. Retaining a stock rear brake setup (freshly machined rotors with Intima Type D pads) did mean the braking was notably more front bias, but the car did not feel greatly unsettled by this. Alpha Omega Racing is currently releasing a rear upgrade kit which will aide in returning a more balanced bias. The recommendation to upgrade to the larger brake master cylinder would also improve pedal feel however I do not feel is ‘necessary’ in my car. This would probably be a different story in a Silvia or R33 GTS-t which both have a smaller unit. The kit originally caught my eye because the Evo Brembo’s have larger pistons and more pad area, while being a cheaper option to the ‘factory GTR Brembo upgrade’. Suffice to say I am definitely happy with the upgrade and will be looking forward to getting my hands on the rear kit. If anyone has any questions regarding the kit, its install, or any particulars about the performance on track, please feel free to ask me either in this thread or by sending me a PM.

I have been running the Alpha Omega Racing kit for the last few events I've competed at and have been extremely impressed, looking forward to fitting their soon to be released rear kit. Going from a stock setup with T3 rotors and upgraded pads to the Alpha Omega kit with the same pads made almost a 2 second difference to my times at Wakefield Park. I have actually just posted a review on the kit as I have had a few members asking me about them, I will post the link in my signature when it is posted
