So after finally destroying my best lap time at Eastern Creek, courtesy of running DJ-01s, i have now noticed i have a bloody big blister down to canvas on my front right tyre.

Obviously turns 1, 2, 8 and onto the straight (10,11,12) stress the right side tyres.

When bolting on the tyres the dealer did advise that the grippier rubber will have me wearing the outside of the tyre, as i wouldnt be running enough camber or toe to get the most out of the tyre (or get the best endurance/wear out of the tyre)

So currently im running : Front - Camber - 2.1deg

Castor - about 5.5

& no Toe

So East Coast will be setting up the front as to not destroy fronts, but compromise is it will destroy my normal road rubber.

So directed at the guys who run the DJ01s, Potenzas, Advan etc compounds, how do you combat destoying EXPENSIVE track rubber with street suspension settings, or do you put up with poor road wear in order to look after your track rubber.

... and for the record i was amazed at the performance increase. I was carrying about 15-30 km/hr more speed thru corners, and car braked a lot better. And this was with a susp setup that would start to understeer after about 4 laps due to the blistering of the outside of the front tyres.

I have the same problem...I have similar figures for camber etc...

I use $110 kellys to drive around on...wear rating of 430 or thereabouts...you cant wear them out I promise you. You just need to take your time in the wet.

2nd option find a piece of crap to drive every day and use the line for what it was intended...going really fast.

By the way how did you decide 2.1 camber was good, just out of interest? How do you adjust your camber?

Originally had more camber in the front, which to drive seemed to help turn in, or give sharper response, except daily tyre wear was terrible. Current 2.1 seems to be a little kinder on road tyres, but obviously not enough for track rubber with its additional grip

      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.
