Hi All,

I've just been looking on the DBA website for some new rotors but it looks like they are only making them for Brembo calipers. I've had a bit of a search and not really come up with much as far as options. I don't want to upgrade my brakes or add spacers/brakets ect ect just to accomodate for the larger DBAs.

So my question is what are my options for keeping the standard calipers, the car's not a daily and I'd like to start doing some light track work with it soon. So looking for something slotted.

Just look for R33 gts-t. Same thing.

Get RDA, better value if you are only doing the odd track trip in a stocker car.

Pretty sure gtst rotors 2mm thinner, ie 30mm while early gtr is 32mm.

+1 for RDAs.

Hi mate,

DBA definitely do your rotors in 4000 series slotted, and for track work would be the ideal option. Made in Australia, high carbon content (for better performance and longer life) and thermal marking paint to monitor track temps. To suit your car are $198 each for the front, and $148.50 each for the rear.

Just look for R33 gts-t. Same thing.

They fit, but they're not the same thing. The GTR rotors are 2mm thicker than the GTS-T. Doesn't sound like much but thermal mass when you're chasing performance is significant.

Get RDA, better value if you are only doing the odd track trip in a stocker car.

They're cheaper, but when being used hard won't last as long as the 4000 series, so some of that cost saving is offset by that. RDA slotted to suit are $349 for the front pair, and $185 for the rear pair.

Going up from that would be something from Project Mu, but the pricing gets fairly serious also.

Any questions at all just let us know!

Regards,

Greg

Ah ok, 2mm - fair point.

You can get the RDA under $300 a pair for fronts if you shop around. Could go through 1.5 sets of RDA for the price of one set of DBA. Comes down to what the end user wants/budget as there is nearly 40% price difference.

RE: Rotor wear. It is as much about pad choice in terms of how long a rotor will last. Get a pad that is hard on rotors, and rotor composition will be the least of your worries.

I've got the new club spec slot 4000series on my 32gtr.

Got the whole set for 600(4 rotors).

Keep looking, they are on the website.

From memory, not with the rest, have to go down the list a bit.

A couple of years back bunch of us had 4000's crack with track use (the thread should be easy to find). Are they any better now?

Yep, it was mainly down to the old slot design. Same reason the 5000 series in the old design never had that extra little slot on the outside that the 4000 did.

I'm in now way knocking RDA (well sell thousands of their rotors every year with never a problem) but when used with an aggressive race or street pad, the DBA will easily pull back the 40% price difference in terms of rotor life.

      Jacks that fit under GTR lips that can reach the subframe?

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.

      BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.

      My experience with Rising Sun Exports Before agreeing to the sale I tried to do as much research as I could (obviously), his Facebook reviews are 98% and he goes Live at least once or twice a week. I contacted 2 people in the UK who had used him for their imports, both had positive feedback. His explanation and talk through of the import process was thorough, answering any query no matter how stupid it was. It felt as soon as the money was sent, communication dropped off. I asked for shipping updates every 2 weeks or so, not wanting to pester him, he never had any updates. I wasn't informed the car had been dropped off at the port, I only found out by his Facebook story. I asked for the photos taken at the port, knowing he would need some for insurance purposes. I received a few 5 second clips and that's it. When asked again, he said his staff had them. Weeks later I asked again, he tells me he doesn't have any, but does have 50 photos from the original advert. I never received them. I eventually got the documents sent via WhatsApp after I mentioned the port was requesting them. I purchased a CarVX report, to find out the vehicle is a Grade R with recorded accident damage, first recorded in 2017 when it was first auctioned. He never told me the grade, then again I didn't ask. His response was "Grade R means nothing, it wasn't chassis damage". Still, I would have liked to have been informed about it. Jon prides himself on being open and honest when it comes to inspecting cars, it's his main job doing so at the auctions for customers. When the vehicle arrived in the UK I noticed a few little cosmetic issues. It's a 21 year old car so it wasn't going to be mint condition. The side skirts are cracked on each corner and the sealant is failing. The front grill on the bonnet/hood isn't secured very well, mounting studs are missing. Both minor things, but again, it would have been nice to be told. During a Facebook Live walk around video of the vehicle, he mentioned it has a front Whiteline anti roll bar/sway bar. While on the inspection ramp, I noticed the stock item has been installed. When first questioned, his response was "the ARB? Switched? Since when, it never had them". Since sending video and photo evidence I've not received a response. I'm probably being over critical of the overall condition of an old car, but all I wanted was honesty (which he claims to have). I'm aware I wasn't his only customer, he's busy doing XYZ but other reviews praise him for great communication with regular updates and photos, I felt I didn't receive the same treatment.
