Moving from Street to Semis?

[Cal]

Grumpy's 205 on semi-slicks was a revelation! It was super quick round the Old Pac, even with the old standard engine. It really impressed me how quick it was with that combination of handling and grip.

That's the Pug chassis, not the tyres.

Its not just the car. Semi slicks make a big difference on the old Pac Cal.

That's the Pug chassis, not the tyres.

The tyres made a HUGE difference Cal. So much more neutral in the handling. Less inclined to oversteer.

[Cal]

Yeah I know, but fit semi's to a shitter and you still have a shitter.

As the smartarse AXGT pointed out, I got to experience oversteer in the Pug coming down Mt Glorious :oh: scared poo out of me.

I lowered the car, stuck on the Azenis and didnt that make a difference, funny thing was, when I, err, "aquired" :D the 15" rims that had Goodyear F1's on them, the actual grip level didnt seem to drop, I was sure they would break away sooner than the Falkens and was very cautious when I first went for a belt around the twisties, but they work quite well.

I guess you can drop time with tyres on the same set up on the same car, but chasing a set up seemed to work ok for the Pug.

Thanks for the replies.

Yes, the car fuel surges on left handers with less than half a tank, and also, how do i tell oil surge??

[F|sh]

the oil light will come on.

Or the oil pressure guage will just either go up to a hi pressure or drop to a really low pressure as you hit the skids.

[Matty]

as for "learning the car again" - a bit, yes. depending on the tyre it can be a bit less progressive at the limit, and you don't get as much slip angle to warn you that it's close to the limit.

Basically, your responses through the steering in particular have to be much faster, or it can get snappy on you.

I can strongly recommend bridgestone RE55's or the older RE540S's both semi slick and DOT approved. Excellent tyre

[F|sh]

i found the RE540's to go very slippery when old. the yoko's seem to keep there grip through out.

[Camma]

Anyone know a tyre retailer in Canberra that specialises in getting some decent road legal semis in? Trying to find one that can get a set of RE55s, DZ02Gs or similar in. It seems as though everyone can get the Azenis in but nothing else (or couldnt be arsed).

[Guido]

I am pretty sure the R888's are dot approved. Does not really worry me though as they are on a second set of wheels that will never see the track anyway.

[CT]

R888's are DOT approved - I used them in the Dutton last year. They replaced they R881 which was also DOT approved. I prefer DZ02 dunlops myself.

[F|sh]

hmmm

then why did the toyo guy say they weren't. That must be america then.

[PHULL]

aaa

I would do a 2:29 at phillip island on yokohama 539's on a greasy oily track (first time ever on the track)
and could to 2:07 on a pair of old bridgestone 540s (82 Mazda RX7 13b ep) a year later. I know I can do better
