Interesting. You may like to try raising the front up. I use 355 front, 345 rear. The more nose down it goes the more it understeers.

Secondly, with regard to camber there are two sorts. Static camber, ie measured at rest & dynamic camber, measured when the thing is loaded up through the corners. However much static camber you car may be running you seem to have insifficient dynamic camber. This is shown in the photos as the front wheel "tucking under" during cornering. Anyway, form what I understand, this is a suspension geometry issue tiedlinked to too low a ride height.

So it would be worth (IMHO) trying the car with an extra 15mm in the front ride height.

Anyway here is mine cornering - note the soft springs (Half your rate) but the front tyre -ve camber is still ok, even though the static is only - 2 degrees. I awill be chucking some harder springs at it today/tomorrow.

Nice car by the way Richard

I would go much less camber than that. Around 3deg front and bit under 2deg rear.

As for dynamic camber, the rate at which it increases really should be greater if the car is lower, so I dont think that's the problem for insufficient camber.

Do you know the actual amount of static camber you have at the moment?

i asked for neg 5 when it was done last.

Car is going back for another alinement next week which i will watch it being done.

I have also been speaking to Bridgstone here and the motorsport guys are going to come back to me with some setting that should work for a heavier car. Lucky as these guys are a sponsor of the track where we race and had done a lot of development in the compound for this tyre.

:-) Also were none to please to hear the pilot cup sport was faster

As far as I know (ok, I don't) you cannot adjust the front camber with the Cusco arms - there is no mechanism.

If you have Bridgestone blokes there then please pummell them with the questions of the day:

Hot set pressures for the RE55's on the Gt-R's & optimal operating temp for the tread face.

Ok have a operating temp of 60 degree for the RE 55s hard compound which is the compound used/developed for the very sandy conditions we have here.

pressure will depend on the day i would guess but we are in the low 30's here at the moment so not so far removed from sunny QLD

i will keep you in the loop.

Interesting. I asked because the conditions you have over there are probably pretty similar to what we have in WA come summer. Both temperatures & the amount of sand.

      RB20DE NEO smallbox clutch.

      By Kapr · Posted

      For once a good news  It needed to be adjusted by that one nut and it is ok  At least something was easy But thank you very much for help. But a small issue is now(gearbox) that when the car is stationary you can hear "clinking" from gearbox so some of the bearing is 100% not that happy... It goes away once you push clutch so it is 100% gearbox. Just if you know...what that bearing could be? It sounding like "spun bearing" but it is louder.

      Yeah, that's fine**. But the numbers you came up with are just wrong. Try it for yourself. Put in any voltage from the possible range and see what result you get. You get nonsense. ** When I say "fine", I mean, it's still shit. The very simple linear formula (slope & intercept) is shit for a sensor with a non-linear response. This is the curve, from your data above. Look at the CURVE! It's only really linear between about 30 and 90 °C. And if you used only that range to define a curve, it would be great. But you would go more and more wrong as you went to higher temps. And that is why the slope & intercept found when you use 50 and 150 as the end points is so bad halfway between those points. The real curve is a long way below the linear curve which just zips straight between the end points, like this one. You could probably use the same slope and a lower intercept, to move that straight line down, and spread the error out. But you would 5-10°C off in a lot of places. You'd need to say what temperature range you really wanted to be most right - say, 100 to 130, and plop the line closest to teh real curve in that region, which would make it quite wrong down at the lower temperatures. Let me just say that HPTuners are not being realistic in only allowing for a simple linear curve.

      I feel I should re-iterate. The above picture is the only option available in the software and the blurb from HP Tuners I quoted earlier is the only way to add data to it and that's the description they offer as to how to figure it out. The only fields available is the blank box after (Input/ ) and the box right before = Output. Those are the only numbers that can be entered.

      No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.

      God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
