D2 rear brakes arrived today, was originally going the G4s but Darron at just jap

suggested that the D2 were a little bit easier on the eye, otherwise the same, also had these in stock.

accidently sent me the rears instead of the fronts, but i reckon he was just ensuring i would buy both sets lol.

darron was excellent, cant fault just jap service.

weights of engine & transmissions have been talked about alot in this thread, but today i weighed a few components thanks too 'Victory' bringing a set of scales in.

we worked out a few weeks ago that a stock standard LS2 weighs 90kg. That was with standard cast iron exhaust manifolds.

The tremec 6 speed complete with shifter, slave cylinder & release bearing weighed 62kg.

unfortunately i didnt weigh the old clutch & flywheel assy, but should have saved a couple of kilos there as the old 12" clutch was massive with the cast flywheel. Know running the steel flywheel with 10.5" clutch.

For a comparison we weighed a RB20 5 speed. It weighed 39kg minus shifter. Ill weigh the clutch and flywheel assy tomorro. So i reckon a rb25 turbo box would weigh around the 50-55kg mark. so i think i may be giving 10-15kg away in transmission weight but be ahead 50-60 in the engine department. i have a rb25de in the shop to weigh once we figure out how to do it without breaking the scales. might have to use some scales from the butcher or fruit shop lol.

Gary from superior suspension also weighed the stock springs which came up around 6kg each. the new coilover springs weigh 900grams. thats 20kg. but the new disks are heavy so i will be giving some weight back. ill weigh the old & new rotors 2morro.

its a bit of a juggling act but hopefully it has lost and gained weight in the right places.

3D Sports Sedans have a minimum weight of 1125kg, but there is no minimum weight for super sprints so hopefully im under and can add and remove weight when necessary.

weighed rear gtst against gtr alloy stub axles today and there was 3kg difference each side. but probably give that back in drive shaft weight.

also 12kg difference in gtr to gtst bonnets. i thought that was huge.

didnt get a chance to weigh other stuff but will post when i do.

boot mate....wieght those up it will make your eyes water.

I thought exactly the same thing about the new brakes and suspension gear....it is heavier :) but should be worth the trade off.

and yes purple is easier on the eyes....thats why I stole the new d2 calipers and replaced the g4s on the stagea...then put the g4s on the race car rofl. they all bolt on the same adapters and are interchangeable.

what are you doing with the handbrake? looks like the d2 rears don't have the handbrake. are you going to tap in a hydraulic one or just not bother.

handbrake doesn't really matter on an n/a race car (you can turn it off and leave it in gear) but in a turbo car you need a handbrake to hold it if you want to leave it running to cool the turbs down.

yeh rotors are definately heavier, 8.6kg each. rears incorporate handbrake drum into the hat so no probs there.

Callipers wouldnt be much different. also save 5kg a corner with the coilovers, so most of should even out.

cant wair to weigh the whole thing finished so i actually know where i stand with it.

    • The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.
    • When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.
    • Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.
    • This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.
    • Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
