I called Craig at Hornibrook Motorsports. Doesn't look like anyone makes softs in such large sizes. I guess they figure they're for big heavy cars that need a harder tyre. If Toyo RA1's are available in that size it might be the go.

or maybe you could run slicks? the AWD turbo class doesn't really have any rules... it only exists at Mt Cotton. Otherwise, Stuart Inwood ran his GTR in Sports Cars at the Australian Hillclimb hampionship . Slicks are allowed in that class, but he was on semis.

true, plenty of GT3 Cup Cars with lots of dunlop and michelein slicks around that will suit your size. cheap cheap! forget carrera cup though. look to prod sports. the guys we used to run with there have lots of dough and go through a set per session and will practically give them away (well compared to what they cost new).

I can't remember what sizes we used to run, but they were staggered front and rear (around 255 front and 285 rear). you could probably run a set of rears all 'round on your thing. most guys I know who buy them second hand buy fronts only as they are generally going on 9 or 9.5 inch wide wheels and the porshce rears are too wide. more left for you!

harry can't we use slick's at mnt cotton hill climb?

yes you can. the question is if they're allowed in the AWD turbo class or not. That's a class MG Car Club created themselves to get the fast modern cars out of Improved Prod and Road Registered classes to give the old bangers a chance of winning something! It doesn't exist in the CAMS manual so it really have any rules. You *should* be able to run slicks.

If they won't let you run slicks in that class, you could always run in Sports Car or Sports Sedan class. Stuart Inwood ran his GTR in Sport Cars Closed in the AHC last year, so they're definitely eligible for that category. And they are now also eligible for Sport Sedan category, both of which permit the use of full slicks.

on the RE55S, I've only used the SR compound, which i think is the hardest of their compounds. So I can't really comment on whether the Toyo is softer than the medium Bridgey. As for the Dunlops, I haven't tried them myself. Maybe a helpful tyre store would allow you to poke a durometer at a couple of new tyres? You can make one easily enough - it won't give you an actual duro reading, but will tell you which of two tyres is the softer compound.

      Well, this is probably where a wiring diagram and a multimeter come into play.

      gauge needle removal

      I can say to anyone thats doing this; having done a number of R clusters; just be careful if its an unknown cluster.  It takes a bit of force to pull up; but if it feels excessive then its probably stuck. I've had this and pulled the entire hair spring out; and I can tell you; its not easy getting the correct spring replacement with the correct inner diameter and winding. In my case someone had used some sort of adhesive to stick it to the spindle and it pulled the whole spindle out; which the force seperated the hairspring from the spindal and caused it to deform.  You may have to clean it (IPA); or in my case if i'd known i should have used some sort of solvent on it.  Also check out Cruizin Central on eBay. He does all sorts of dials; and you can email him with any custom designs you want. So if you want like certain logos etc...he'll send you a mock of what it will look like then you accept the order and he'll take care of the rest. Fantastic dials and he can do basically any design you want.

      R33 GTST Axles

      By Jarsky · Posted

      Have you confirmed its the actual axles? Also the wheel bearings that mount on the hubs to hold the axles wear out. I replaced mine as they got play in them. It sorted my play issue.

      R34 Speedo not working after manual swap

      By Jarsky · Posted

      Ive converted a few clusters for the R33 with 320km/h dials. On the back there are some pads which can be bridged or unbridged (using solder or wick braid) to calibrate it. There is one bridge which is for MPH <> KPH; and there are combinations of bridges to offset it. There is probably a diagram  For example; this is my conversion for a 180km/h dial to a 320km/h dial (I put custom GT-R dials on it with the GTS25t layout) If you have J2 soldered (assuming the S clusters have a similar config to the R clusters); you may need to remove that solder

      DeAgostini 1/8 scale BNR32 Nissan Skyline GT-R Nismo

      Back on topic 😉, these are some of the notable pages from the booklets that are supplied with each weekly parts update. I never knew the BNR32 test mule car had an S13 Silvia front end... *Edit: On closer inspection the test car still had the R32 body, but only the front end had Silvia panels etc.
