yer the 32/33.5 is an experiment and the harder tyrer does seem to be giving better response, but at the expense of contact patch.

it actually felt ok in the dry on the way to work today, but not right. i was getting an acceptable feel the wrong way.

 

i've always tried to keep to the 30/33 in the past and it's always been good.

however it was giving a sluggish feel at the front which always feels like the soft tyre waiting to catch up with the input.

 

33/35.5 were the pressures i found i had when i thought i had them right in a cold snap of weather a year or two ago and not what i have now.

 

i may try 29/32 in a few days and see what happens.

 

first tho i've got to empty the water of out of my right front, igets at work used the airline for a water hose and didn't clear it out after, took a second to work out what was happening, not much in there but it's now got a tiny wobble at 65.

put 32 on the front and brought the rears from 32 to 33.5, temp has dropped nearly 10c in the last week or two so guess they dropped a fraction. temps also not helping traction.

innitial impression over the 11 miles home, feels like i'm riding on the ball of the tread for sure, tram lined a lot more on a section of bypass thats bad for it.

got used to it, as in not the split personality of the 30psi, response is better but feels for sure like their too high and the contact patch.

 

will have to try it over the next few days in different conditions and speeds.

 

last time i had something similar i'd done my pressures when the temp was around 3c, and when it got back to where it was now the fronts were 33 and the rear 35.5, reading back the car was behaving similar, drifting with torque steer was an issue, but i also had cheap and nasty tyres that came with the car.

the gutting thing is i know what these dunlops are like and i just feel like i'm buring off the best of them with this.

still not happy with this, sometimes just not quite right.

steering around the center is a little dead with no innitial response, turning right it's progresseve until you get understeer, which happens a lot sooner than it should.

turning left the dead center turns into a fair amount of bite which catches you out as it was dead at first, this then also turns to understeer at about the point you'd expect, however thats if the mid turn bite didn't catch you out and you've got more lock on than you actually wanted.

if it wasn't for the dead center and it reacted quickly it'd be about right.

 

it's the sort of thing i've had before with low pressure at the front, but by the numbers it's spot on. i may up it a couple of PSI halfway to where the garage had it and see what happens.

 

i suspect it's still a LHS issue as turning left isn't too bad once it's loaded on the right

just a note.. i realise the negitive figures do mean that both wheels should be pointing towards each other at the top as it's from a center baseline, but the graphic chart you get suggests the RHS leans out... however despite the negitive figure the line is in the positive side of the range..

 

weird.

wheel alignment was done yesterday.
the changes were that slight they didn't charge me.
only real change was front left camber from -1.05 to -0.54 ( both within limits )
and front left toe from -0.03 which is a fraction out by .01 to 0.03
they also had a play with the pressures.
I didn't really get to try it out at NSL speeds on the B road home but it felt better, but what I had now was an overall lack of grip but it was balanced, which made me think they upped the pressures all round, remember before i had them spot on.

checked today and sure enough all were at 34-35.
dropped them back to 30 front 33 rear and it's pretty much how it was before the clutch change although again thanks to the slow !Removed! brigade i didn't get to try it on bends i know well at decent speeds.

only thing i notice on the print out is my right front camber is -0.28 and to my thinking both fronts should be leaning into each other, not both leaning to the right slightly.
should i not be matching the other side and have that at 0.54?
