hey eric

doing the same thing as you actually.

After alot of research i found that you wont notice any difference between RDA and DBA on the street. The RDA are a softer disc so they will wear quicker, however, they are alot cheaper. As you would of seen on the rda group buy. So its probably best bang for buck if you went with the RDA discs. This, in the end, is what i chose and have just ordered with the RDA group buy batch 49.

I got told the best combo if what your doing is mainly street driving is RDA slotted with green stuff pad. Which is a less aggresive pad so it wont eat away at the rotors. They are more than capable of a few track days here and there. But if your after a tracked only car the you would have to go red/yellow which are made from harder compounds.

Just my 2cents

hope it help eric.

Price wise with slotted discs, DBA (something like $480 for fronts to suit my car) are close to twice as much as the RDA equivelent ($270 for fronts to suit my car). It's really up to you if you want to pay nearly twice as much for virtually the same product. $500 (for my car) is in Endless (slotted) front rotor territory imported from Japan.. so if you were willing to pay that much I would choose Endless over DBA.

i used the DBA series 4000 slotted rotors last year for track/street duty, and i had no problems, they dissipate their heat pretty well

as long as you don't use cross-drilled rotors, and over-heat them there's no problems

I did a brake upgrade with RDA slotted discs up front with green stuff pads and I think there pretty good. Ive had them for about two months now. Also worth doing is putting some good brake fluid, dot 5.1 is what I put. And I also put adr braided brake lines all round.

If you get the RDA slotted discs its probably better spending the extra money on the gold something discs coz there apparantly more rust resistant. Looks better under the rims.

DBA a few years ago, I had issues with them crazing. Now they seem to be better quality. Last set I used were 4000 slotted's with 400deg, then 500deg pads and they held up well on two trackdays as well as daily duties. Still A1 when I pulled em off. Pulled em off because I upgraded to a larger rotor setup.

RDA are good for street, but after seeing how they perform on a mates car, I wouldn't track day them.

Stay away from bendix ultimates, they chew your rotors a fair bit.

Stock nissan drilled discs I bought for $160 each from nissan were okay for light street duty, but cracked over time running ultimates, couldn't take the heat!

      You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.

      By cosline · Posted

      Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik

      Spotted on the street....

      By Rezz · Posted

      Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
