Hi peeps.

Im taking the car into heasmans on thursday to have the adj whiteline kit alligned to whatever specs i want.R33 gts-t

But the thing is i dont know what to set the car to for a regular streeter/occasional track day warrior in terms of degrees of camber castor height toe etc. for the front and rear.Ride quality doest phase me in the slightest.

This is the way i see it so far.

Castor=7-8 degree's.for fast turn in.

Front camber=1 degree

Rear=1 degree

Toe out on the rear??questionable on what i should run.

A little toe in on the front.Again??

The car sits at 350mm and tyres are 17/235's at the front.And 360 mm at the rear on 17/255's.

Im thinking i should level out the car to 350 all round what do you guys think.

Most of all!-->What do you think SK.

:(

Craig.

Hi Craig, my suggestions;

1. Don't specify a caster target, get Doug to get you as much as he can. You can never have too much caster on a Skyline

2. Front at 1 degree negative camber is OK, a little more won't hurt on the track. Road use tyre wear becomes an issue over 1.5 degrees negative

3. 1 degree on the rear is OK for the track

4. Do you still have the HICAS connected, if so a little toe in would be my choice. If no HICAS, then I usually aim for zero toe, especially on higher power Skylines. They don't need any help, they oversteer on demand.

5. Front toe out is good for turn in, about 1 to 2 mm per side

6. Skyline front guards are cut higher (~15 mm) than the rear guards, so flat (no rake) would be 350 mm front and 335 mm rear. Personally I like a bit of rake, arond 10 mm nose down on a 2wd and 5mm on a 4wd. So 340-350 mm rear would be my target. The rear negative camber is very sensitive at that height, so it may be necessary to go up to 350 mm to achieve the target static negative camber.

Doug knows what he is doing, he will achieve the best he can and remember every car is different.

:D cheers :D

      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.
