From memory the stone guards (Which is what they are) are a press fit onto the hub? Not sure you can just replace them. Most people cut them - either just a trim as necessary depending on which end of the car you are talking about or remove them completely. As far as bolts are concerned. R33 Brembos use 12mm, 34's 14mm. The thread pitch is different 1.5mm for Brembo as opposed to 1.25 for the Sumitomo calliper.

Yeah just ignore the fact that Herbert had vastly more information to hand than DC. Not that it mattered anyway. Massa has another bollard off the track he was forced to go and smash his suspension on. Guessing that was Hamiltons fault to. Massa is, in a way, lucky that Hamilton keeps running into him. Serves to divert attention from his profoundly ordinary performance all year.

Cams Approved Fire Extinguisher Bracket
djr81 replied to DattoP510's topic in Motorsport Discussion & Builds
Joe, just to let you know I fitted mine up and yes it fits an R32 GTR nicely. -
This from Cams SCHEDULE B – BONNET RESTRAINTS The Board noted the recommendation of the Australian Sport & Club Development Commission that within Schedule B for road registered cars, a standard two stage fastener would be appropriate in speed events such as supersprints and hillclimbs and the regulations have been updated to provide clarification. It is common practice for many competitors in speed events to fit a retention device under the bonnet, this type of fastening will be specifically provided for and may be used in speed events for non-road registered vehicles instead of the requirements for race meetings. These changes and clarifications are designed to encourage participation in these predominantly club level events and will be implemented in the 2012 CAMS Manual of Motor Sport.

Bilstein - Coilover Conversion
djr81 replied to simpletool's topic in Suspension, braking, tyres and drivetrain
Installed the 8" springs on the weekend. Photo below is of the old damper rubbers - or what was left of them after taking the full weight of the car for a number of kms. So if you have this set up ie standard tops & a spring cap under the shock rubber dont be surprised if your ride height keeps disappearing. Unmangled rubber is next to the two stuffed ones. Anyway as regards to spring selection the 8" fits fine. The 10" I wouldnt recommend if you want a low ride height. If you cut the extra grooves into the damper body then you will be fine with a 10". The threaded section is approx 120mm long. Bump stops are dependent on ride height. I reused the stocker but it is probably a bit short to be honest. Made up a 55mm od 3mm plate to sit above the bump rubber and below the strut top which appears to work well. Koni make nice bump rubbers but not sure who else do. Anyway I highly recommend all this - worth the effort. As an aside to get the bump stop length correct you need to install everything then measure how much shock travel is left - compare it to the remaining spring travel and then trim the rubber to suit. So the stuff I needed/used on the front: Bilstein shock B46-1471 (or 1472 either or one is front one is rear from memory) 8" Eibach spring 0800-250-275 (8'/200mm long spring, 2.5"/65mm ID, 275lb in/5.1kg mm spring rate) ISC rubber top mount. 120mm long threaded section. Spring perch. Spring lock nut. Machined up parts were a new smaller id bush for the strut top to suit the 10mm section on the Bilstein shock and a plate to sit on top of the bump rubber as the washer supplied by ISC looked a little small for what I wanted. -
Nah and Im not either. Just trying to point out you shouldnt confuse PR bullsht with reliable engineering. There is much more to an engine install in an F1 car than horsepowers on a dyno. Honda had to learn that. Ron Tauranac showed TWR (of all people) that with the Yamaha in the Arrows. Not that it needed proving but the Renault motor has also proved it over the last few years. If you want to see a good motor have a look at some of the massive aluminium Chevs McLaren used in the M8's and later. Or the Repco motors in the Brabhams. And yes I am an MRD/Ralt fanboy.
-
The point wasnt really whether or not the motor somehow once or even twice hung together for the length of a GP. Really McLaren went from belting everyone with a Honda motor to being thereabouts competitive with a second string Ford to being hopeless with the Pug. It got worse in the first year with the Merc - even the fat boy special they made for Mansell was hopeless.

Mugen was founded by Soichirio Hondas son. They damn near won a WDC in the Jordan with Frentzen of all people. Yes kiddies. They started with all sort sof oddball stuff. Got good with the DFV's, spent huge amount of TAG money to get Porsche to build the V6 motors from 83 - 87, then went Honda, Ford, Peugeot, Merc. Bollocks I say. Everyone was down on the Ford motor. But the packaging advantages and the massive torque made up for the hp deficit. Not that it was ever what the French made it out to be. In any case the engine McLaren ran was to an older spec than the one in the Benetton. True story.

Thinking Of Starting My Own Mini Superlap
djr81 replied to fatz's topic in Motorsport Discussion & Builds
The Luke Youlden Understeer of fail award. The Quade Cooper Award for services to New Zealand sport. The Sebastian Bourdais award for the biggest fkwit who happens to share his name with another fkwit. The Graeme Bailey award for best transformation from chicken choker to legend. The Niki Lauda award for best flamage. Oh and can I enter my Chev Corvair if the fitment is aggressive enough? -
Bilstein - Coilover Conversion

Shown attached are the front & rear shocks with 8" and 10" springs and the ISC strut tops on them. Not 100% sure which will fit best prior to actually putting them on the car, however it looks like the for the fronts an 8" spring is the go & a 10" for the rears. Obviously it depends a bit on the spring rate - the higher the rate the shorter the spring you will want and also on the ride height. The 5kg/mm front is not brilliant for travel so I will try & get a 10" spring in there. Should fit (just) but any higher on the rate and you would go for an 8" anyway. -
Why do you want to remove the harmonic balancer to replace the cam gears? He said gears and that was all he asked about. Other stuff is a different story and yes fan & radiator out but if he only wants the cam gears done he doesnt need to dismantle half the engine.

Pics Of Your Car At Or On The Track
djr81 replied to hamiltonau's topic in Motorsport Discussion & Builds
Nah rally stuff makes you look like a muppet. There you are trying to read the notes and the bloody photographers make it look like you are trying to find a spot under the dash to hide. Second one from Wanneroo. Note the multiple black lines & the Emo with the fail understeer. -
Yeah all of that except the fan and radiator.
-
Good trolling. Quote someone without context & take the relative reference in the said quote & make it absolute. Win, win.
-
Seriously if you find a stock one keep it that way. There must be atleast two of them left in captivity. Most GTRs have been modified and yet most people want to buy a stocker to modify. So the best answer is often to get something someone else has spent coin on. That said I wouldnt mind a stocker and Id even try to keep it that way.
-
You are both trying too hard. Back it off a notch (or two) and make it so that the effort is sustainable over months/years etc. You will still improve - just with less effort and over a longer period. Otherwise you will get fed up and end up back where you started. Or injured. Or both.
-
You two are kidding surely? Refuelling is rubbish on the following grounds: It costs squillions to cart all that crap around the world. The car set ups are fundamentally less compromised as you dont need to make a car work on high & low fuel loads. which makes the racing more predictable. The racing is even more dire as no one bothers over taking they just wait for the pit stops and pump in some quick laps.
-
I figure when it gets to the point that teams wont run in qualifying there is something fundamentally wrong with either the tyre design or the allocation or both. Plus it makes Pirelli look like muppets which must be wonderful for them given how much coin they would be spending.
-
So in other words the system requires the officials to work out how best to implement it on a race by race basis. Or in other, other words provides yet more scope for their incompetence to fk up the championship. Easy answer - get rid of it. Oh and the useless "race tyres" whilst they are about it. The less fake plastic "racing" there is the happier I am.

From 1989 to 1994 the R32 was fitted with Sumitomo callipers that used the 296*32 + 292*18 rotors. The exception to this was the Vspec version that used the Brembo calliper & 324*30 + 300*22 rotors. So the date listed in the DBA cattledog is wrong for the end of the smaller rotors on the GTR, ie it didnt end in Aug 93. Look at the calliper & you will then point you in the right direction. The only way it would be wrong is in the extremely unlikely event that the previous owner has adapted the Sumitomo calliper to the 324 rotor in which case there will be an extra adaptor on the calliper.
-
The FIA asking themselves? What? These people are highly trained professionals who dedicate their lives to fcking up motorsport. No need to ask themselves anything - the answers are all coded into their DNA.
-
Dont mention the war. I mentioned it once but I think I got away with it all right. The reality that it takes even the likes of a gold plated genius like Adrian Newey a while to get a team sorted to produce a winning car. The REd Bull would be a championship winning car with any of the leading drivers in it. The only change this year is Webbers marked inability to cope with the Pirellis.

Yeah 15mm OD, 10mm ID & 32mm long. Same front & rear. Going to send mine to get plated. -
Bilstein - Coilover Conversion

Maybe but not with those strut tops. The standard shockies have the seats on them for standard springs - the id of which is much larger than the 65mm the ISC tops work with. May work with other brands of tops but you wont be getting any height adjustment anyway. -

Front pair turned up last week. They are $199 for the type with the rubber bushes. Spherical ones are more. The gain in shock travel is just under 30mm and the strut appears to match a 200mm long spring pretty well and hopefully a 250mm item. They look to be a good improvement over the standard tops, even if you just do the front pair. Worth the money.
