Bnr32 - Track Only Build
djr81 replied to $$slowmedown's topic in Members Cars, Project Overhauls & Restorations
Just trying to understand the idea. Standard as possible and track don't usually go together. What track stuff are you doing? -
Compressor is bigger than the clutch. Nice.

They have to keep the doors open somehow. Not like they are getting any useful sponsorship from other than the pay drivers.

Good Places To Buy Second Hand Rims Locally
djr81 replied to djr81's topic in Suspension, braking, tyres and drivetrain
There were some new Enkei's RPF1? for $1300 ish plus shipping which I would be ok with. First preference is to match what I have 17" titanium CE28's but they dont come up that often. Last time out I bought a pair with tyres in good nick for $750 which in retrospect may have been a bargain. Problem is because of the fitment thing everyone has 18's and hella flush offsets. 9.5" is the default width now it appears. -

Yes x 2. Nobody really bothers looking at the WTB stuff. http://www.sau.com.au/forums/topic/441306-wtb-rays-ce28n-17x9-titanium-silver/#entry7244727 -

Sorry but I don't have a facebook. Guess that is where everything has gone too which doesn't help. -

Yeah been looking at Import Monster. Same same week after week and nothing I liked -
This thread makes no sense. What is stopping someone running 35lb? Stage 2 cams are all that is usually needed but it also depends on the turbo map - is it a Mercator projection?
-
They all are.

Also, w a n k e r s. https://uk.eurosport.yahoo.com/news/formula-1-big-teams-sacrificing-income-135324887--f1.html Are these not the same people who wanted to redo their engines at a cost of how ever many million dollars? W a n k e r s.

That is the thing. They are so far in front that no one is putting any pressure on them. So mistakes aren't made under pressure and aren't punished if they are made.

Acquiring Sydneykid Suspension Setup
djr81 replied to Taso84's topic in Suspension, braking, tyres and drivetrain
For as R32 GTR with Bilstein shocks, from Bilstein. The front shocks, if they are as per factory spec, will support a spring rate of about 10kg/mm. While the rear, again at factory spec, will support about a 6kg/mm spring. -
They dont. But they do driver training and the instructors know their stuff. Also there are plenty of 33's at Wanneroo and I am sure youll get some good advice from there.

You a WASCC member? Good place to start.

Out of interest do you have the graphs and or the shim stack details and would you be willing to share. I have floating about the acceptable range for the Bilsteins for an R32 GTR but not for a GTST. Will post them when I find them. -

Probably in the range where you would look at revalving. Best to ask Bilstein and share the results. -
Don't get caught thinking that you need hard spring on your car for it to suit the track. For example my GTR has 5kg/mm & 5.5kg/mm springs on it. Most China sets you will find have X & X-2 or X-1kg/mm spring rates front and rear. A case of monkey see, monkey do I would think. Few of the new suppliers would bother tailoring or testing their product much. That may sound harsh but is it more likely they all found the same solution, albeit in different coloured anodising? Hardness of the spring does not correspond to hardness of the driver. In any case you can change spring rates within a range to suit your preference. There just isn't a problem going a kg or more either way. For example you can ring Bilstein and they will tell you the range in which they reckon their dampers work - it is surprisingly wide. The MCA's are adjustable in the damping rates so you would think you have more scope. And springs are cheap, probably one of the cheapest components you can get - so you can get it a bit wrong and it is not the end of the world. For info: Nismo S Tune Suspension for an R33 gtst. Lowers the car by around 20mm. Spring rate on these are 5.3 Front 4.8 Rear.

Digressive - but it doesn't mean linear is all bad. Uniball have a reputation for a short life - followed by creaking/clunking. Mostly this is the cheap end of the market and the MCA's are specced better (See their website) But to be honest you just don't need them so why take the hassle on board is you don't have to?
-
Its the age old issue. You want a good result and learning can be half the fun. But learning by making every mistake in the book isn't so much fun. Or cheap. You could do a lot worse than the MCA stuff. You could do a lot worse than a Bilstein shock and Eibach spring combination. I would, at the least, talk to MCA. I am guessing the talk here is about their Blue series? http://mcasuspension.com/blue-series/ Among the question I would ask are: What are the spring rates he recommends for the 33 GTST. Is the valving linear/digressive? Ask if there is an option to replace the uniball with a rubber bush. Are there sway bars he recommends with the shocks - also castor/camber/toe settings and do you need many bushes to achieve those? I wouldn't expect he would offer these over the phone but it is important if/when you buy them. Owmuchisit.

The hard part in learning is being able to establish what is good, as opposed to what is better. For example, a second hand set suspension set up may be better than stock. But how close is it to being good? And how, if you are learning, will you know if you have got a good set up or not? I don't have a good answer to that because I have been caught many times thinking something was pretty good only to make a further discovery/change and the realisation that it was, in fact, pretty crap. Having a trusted supplier of equipment or the opinion or someone in the industry can help. But I have never met someone selling stuff who don't think its the dogs bollocks.

Why the hell don't they just paint them orange? Worked before.

From Bilstein: What difference is there between BILSTEIN B6 Sport and BILSTEIN B8 Sprint shock absorbers? The BILSTEIN B6 Sport is a mono-tube gas pressure shock absorber designed to dampen wide-ranging vibrations very precisely. Where an oil shock absorber produces an oily foam and creates a spongy driving feeling after a very short distance, the BILSTEIN B6 Sport remains constant, precise and stable. The BILSTEIN B8 Sprint is a mono-tube gas pressure shock absorber specifically designed to be used with lowered vehicles with shorter stroke. It also offers the same advantages as the BILSTEIN B6 Sport shock absorber. -

It depends. The biggest problem is getting a decent amount of travel t the front. I would recommend Eibach 65 dia springs, 5/5.5/6 kg/mm front and depending on your preference probably a kg/mm softer at the rear. Use 10" spring if at all possible and make sure you get some strut tops as without them the suspension travel is hopeless. -

Sorry, should read. My shocks have the following on the stickers: Front F4-B46-1471-HO Rears F4-B46-1472-HO They are, apparently, the old part numbers.
