Yeah but to be fair the 1990 R32 was very short on development. Have a look at the photos of the thing in practice at Bathurst & the nuts wheel alignments that is was running. (Only one car that year by the way. Skaife wrecked it at Adelaide AGP not long after) By all accounts it was a horrible thing to drive at Bathurst that year. Also take with a vary large grain of salt anything that was said at the time about the engineering/competitiveness/operation of the GT-R's or for that matter most of the Group A cars. I for one don't even vaguely believe the tiny horsepower outputs claimed by Gibson Motorsports for the Rb26.

There are many issues when you start playing about with this stuff. For example: Roll centres move (migrate) when the car rolls. This is one of the reasons you need to draw the suspension up. You may well want to move the front and rear roll centres by differing amounts. The centre of gravity (which with the roll centre is what defines the roll couple) is next to impossible to work out. What this means that even with a plotted roll centre you are going to struggle to determine the couple - which is what you actually want to know. Roll couples & suspension roll resitance are different front & rear. But for the purpose of the exercise the chassis is stiff. You need to understand and reconcile these two concepts ie car is wanting to roll different amounts front & rear but cannot. This is very important as it is a powerful tuning tool. There is no point getting the roll centre spot on at the price of making a nonsense of the suspension geometry. Moving the pivot point on the LCA is the easiest way of moving the roll centre - both front and rear. Having tried this (& failed to get a result) I would suggest the best way forward is to get yourself a set of spacers (Front & rear) and then do a bit of testing. The downside of this is it takes alot of time & effort. From which you may not get a result. This is why most people recommend a sensible ride height that stops too much roll centre movement relative to the cog. Theory always matches reality - except when it doesn't. In which case it usually works in the opposite way to what you think. Hell I would be happy if someone could acccurately measure the pickup points for the suspension arms front and rear....sounds easy. Isn't.

Well good luck figuring out how much of a spacer you need.

Depending on what LSD you have try this: http://www.nismo.co.jp/en/products/competi...df/repair04.pdf

Yes they do. All they do is lower the pivot point on the outside of the LCA. There are ones for front & rear. The rear ones are easy enough to turn up on a lathe if you or someone you know is handy.

Please be aware you don't actually need the arms, just the spacers.

Having seen what happened to Garth Tander's missus Mini at Wanneroo last year I can't help but agree with that.

Assuming the tyre widths are proportional to rim widths then you will be enjoying bulk understeer. So maybe fix that before getting too far into spring and shocks & buying tyres. For my ten cents on the the rates if you are on R comps then the kg/mm number should be in the single digits and the front harder than the rear. Just don't get sucked into thinking that a bigger number = better. Doesn't necessarily work like that for springs.

Moonface Racing do them. Which end do you want them for & how much adjustment are you after?

If you check the obvious import sites you should be able to get them for less than $250. Also Nismo make steel wheel nuts in various lengths. they don;t appear to have the little collar on them like the project mu ones, however.

I have some of these & would recommend them above any alloy nuts. It is pretty simple - you don't want them failing. You don't want to have to worry about them failing. YOu don;t want to have to continually replace them. On that basis they are actually pretty cheap. Light too for that matter.

If it is just road undulations then it is low speed. Mostly high speed is for when you are kerb hopping.

Yeah too many pies.

Have you seen how fat he has got so far this year?

Come on Troy - how many times have you seen that happen & go unpunished? It is Webber's stock move most of the time & the rest of the field for that matter.

I was talking to a driver from the vintage car club. He said hydraulic brakes were for pussies. Going massively off topic and talking about the wing I have a few assumptions/questions: I assume the general characteristic of the R35 is midcorner understeer. That being the case how does an increase in rear downforce help anything? The simple answer would be to see a trace of the lateral gees versus distance (or time) to check the shape of the graph or see it plotted versus steering input for a given speed range. Anyway the product looks good. I just wonder how people pick up seconds a lap when I bust my arse to pick up a tenth. It usually means the driver is having more of an influence than the engineering. Typically less experience drivers go better in cars that understeer than with the sort of neutral/edgy set up you need to squeeze the last few tenths out of a lap time.

Depends on what/who you believe. Seeing as you are a McLaren fan - any thoughts on the M8?

It wasn't dodgy. Sure, it wasn't the greatest Williams ever but it was a combination of tragic circumstances rather than a "dodgy" design. Williams Renault's won multiple world championships- both drivers and constructors. And the BTCC for that matter.

Well Williams Renault has a certain ring to it. As does Lotus - Renault. In black. With some bloke called Senna driving. Your Polish mate in the Renault is doing alot better than almost everyone thought this year. His team mate doesn't suck teh balls to anywhere near the extent I thought he would, come to that. Bring back McConville I say. The yocals bore me to tears. The Brits are their usual one eyed selves. Still it is better than Murray Walker when Mansell was around.

The RB26 already has a means of scavenging the blowby gasses that accumulate in the head/block. It is the pipe & PCV (valve) that runs from that back of the inlet cam cover to the inlet manifold. Opens under vacuum (ie closed throttle) & sucks the stuff out into the motor & hence out the exhaust. On the other side a line runs to the suction side of the turbs (from memory). It is this one that sludges up your intercooler & has oil dripping out your BOV's. Alot of people block both up when fitting a catch can - not the way to do it at all. For what it is worth (not much) I have run an R32 R at Wanneroo & elsewhere for some 5+ years. On R comps. Originally an 89 & latterly a more recent model. Other than filling the thing up with 5 litres of oil I never had a problem with the 89 version. For the 94 I had fitted a sump baffle & a Nismo oil/air seperator. The only problem I had with that was caused by a stuffed PCV. In short it is not the problem alot of people make it out to be. As for failed oil pumps I strongly suspect alot of them can be traced to stuffed harmonic balancers.....Yes the 92 & on models have a better oil pump drive which is absolutely worth doing if you are up to your elbows in RB26 entrails. Yes the oil restrictors in the heads are worth doing if the head is off. But neither are mandatory.

The Toleman was actually pretty good. Brian Hart did good engines & from memory some hack called Rory Byrne penned it. The point of my analogy is that there isn't much to be gained in imagining if whatever happens. Anyway your hero, Schumacher, regularly would aim his pole sitting car at an angle & then drive the other front row starter toward the pit wall. I distinctly remember him doing it to his brother of all people. If you really want to imagine something try a big accident infront of twenty other cars all with full fuel tanks & cold tyres. Into the first corner of a GP....At the German GP in the early nineties something similar happened. On the upside Tyrrell got some points that day... Breaking someone tow is not amateurish. It is just something else race drivers do. Or atleast should be allowed to do. It isn't the greatest display of racecraft ever but I don't think anyone is saying it is. What I tried to say was that good racecraft is a large part of what you want to see at a GP. The FIA are systematically fking that over. As for Lewis (or any other driver) being a brat. Well to be honest I don't know that many well adjusted twenty something year olds with legions of fans & millions of dollars. Ofcourse they are selfish, self absorbed & maladjusted. Fk I would be if it were me. Probably already am. Very few top level sportmen are well adjusted. They are intensely competitive for a start which usually means they are pretty damn selfish. As for the Renault - for all the negative comments about their engines they can't be all that bad. Maybe running with less fuel is better than with mega hp. The Cosworths are really struggling & their consumption is reputed to be crap.

I ask you this: Imagine if EVERY one of my Aunties had a pair of bollcoks. Then they would be my uncles. Which if you think about it is also completely irrelevent. The rule was put into to help clean up overtaking rules. It appears to have been extended to now stop the lead car from breaking a folowing (as in behind, as in not next to or infront) cars tow. If you check the results from Monaco in 1984 you will see that another driver was closing down Senna. Racecraft in that race was best defined by Nigel Mansell stuffing his (leading) Lotus Renault into the wall & then blaming everyone/everything else instead of his own stupidity. Now that is RACECRAFT.

Nor is the answer to the lack of overtaking to make the bloke in front responsible for letting everyone through. Homo (or anyone else in that position) should be making it as hard as possible (Within the rules, obviously) for the bloke behind. That is his job, afterall. Remember Hamilton didn't just invent weaving on the straight. It isn't terribly effective, anyway.

Well I can't argue with your Oran Park thing but I would suggest the straight at Sepang is a little bit wider. My frustration is that these days when anything half interesting happens or it half looks like a driver showing a bit of race craft/interest the FIA jumps all over it & the story becomes one of fines/sanctions/warnings, instead of about racing. If you take all the bullsh!t the FIA/stewards have been involved in out of F1 in the last few years there is really precious little in the way of highlights. We now have these god awful ugly cars with all their parameters supposedly set up so they can overtake & it is now worse than ever. Atleast Lotus outqualified Ferrari & McLaren.
