ok thanks guys im going to go with the 8pot g4 set-up from darren at just-jap they have down some track work and have proven results so for the price nothing come close

i have 343mm f40 brembos glowing bright orange on the old pac. so you will neeed some seriose brakes if you plan on doing some trackwork.

not dissing the d4 thingies but..... im not to sure on the materials they use and more importantly the rotors. if anyone has sucesfully got them red hot literaly and not had any warpage/crack issues then go for it :laugh:

Just got mine as well and i must say they are quite well made i was surprised.

Installation instructions are just a little strange but easy enough to work through. Had my old ones off and new items on in about 2 hours. About the only real issue was the best way to secure the brake line so i got some P clips and used those check that the line was not rubbing anywhere and went out and ran them in.

First off i was not too impressed, didn't feel much better than the standard items. So let them cool dowm completely as instructed and when for another run 3 hours later and talk about diferent, big improvement after they had cooled completely and used again, not sure why though. Can feel the pressure of the shoulder straps pushing back at me when giving the brakes a good push now.

I wouldn't trust it to pull enough heat out if only using the stock size rotors. I have my fronts smoking after 5 laps of Sandown with 280mm rotors and R32 calipers in a 1200kg car.

I am using slotted 280mm rotors and R32 gtr calipers with custom pads and after 3 laps at sandown I had severe brake shudder through the steering wheel and brake fade! Sounds like yours are doing better than mine!

Not knocking the product at all, I have no experience with them, and not disputing that Just Jap know their shlt, but keep in mind that he sells them, so he's not going to say they're crap. Having said that someone on here runs them and likes them.

Nismo: Really?? Jeez, guess my project MU pads and rotors are doing the trick then!

      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.

      R32 gtr transmission strength, billet plate

      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.
