Hi,

I'm changing my wheel size, and have a set of 4 Michelin 27/68R18 Slicks. The slicks have lots of tread left (see pics) and have had two treatments of octopus grip to keep the rubber soft.

I'm chasing $500 for the set of 4 firm. I paid way more than that for them and I haven't used them.

Located in West Sydney

It depends on your set up. I run standard blow of valves and they touch when you turn lock to lock. My car is pretty low, and it kisses the top of the suspension when you bounce. I only trial fitted them. Lots of guyd on the UK GTR forums run this size, I just cant be bothered raising it and changing the bov's

These are too tall for a 33 gtr aren't they?

Hey mate,

How old are the slicks?

Looks like they will be good for the LM

Where are you located, I live in Wollongong So not far away and can pck up.

Cheers

Hi mate, I'm not sure on their age. The Octopus grip softens them back up quite a lot. A friend used it too on his slicks and the grip increase was quite noticable.

I'm at glenmore park, which is just before Penrith, along the northern road (camden valley way).

What size wheels do you need?

Big ones.

27 / 68 – 18

First Number indicates approximate tread width in centimeters

Second Number indicates overall diameter in centimeters

Third Number indicates rim diameter in inches

//EXAMPLE

Tire has 27 cm wide tread, is 68 cm in diameter, and uses an 18 inch wheel

Diameter in inches = 68 / 2.54 = 26.8 inches

Approximate* tread width in inches = 27 / 2.54 = 10.6 inches

So, it is similar in size to a 27 x 10.5 – 18 tire in common North American designation

Google is still free.

FWIW a 245/40/18 tyre is 65cm diameter.

Hi, the catalogue states a 18x10.5 to 18x12 wheel is required. I know from experience, and any slick retailer will tell you, they will fit anything from 18x9.5 to 18x12. The 9.5 and 10 inch rims require a psi or two more pressure to stiffen the side wall. I have seen a few guys at csca doing this. I had these fitted to 18x10 rims perfectly.

Still available! I'm back from overseas. Someone must want some near new slicks? I slashed 6 seconds off my Wakefield time with smaller slicks...

    • What 1.5 way? There's no such thing really as a 1.5 way, just different ways of explaining 2 ways with different ramp rates. HOWEVER. In any driving in a straight line your 1.5 or 2 or 1.7 way should have no clunking at all. With the clutch fully depressed the diff should be silent (unless it's welded but I'm assuming it's not). Something aint right here.
    • Clutch is a spec brand, new clutch system,( PP, flywheel, friction disc, etc. pull type) installed 100 miles ago, with no problems.
    • looking for some help and maybe some insight on others experience with a new LSD. R34 GT ran and drove beautifully, but always alot of grip loss due to the open R200 rear end, so I just installed a new 1.5 LSD way into the stock open R200 for a ER34. Simple. Everything seemed right. I test drove for the first time this weekend. as I started to back out the garage the first time slowly with tires straight it sounded and felt like I had a loose or half disconnected drive shaft...that was clucking around loose and shaking entire vehicle, and making it feel like the trans clutch was spontaneously slipping then grabbing very roughly while just letting out pedal slowly. I backed it out went to pull forward with the same noise, shake and slip grab feeling with hesitation, I turned the tires to back out more and then pulled ahead some same thing but worst because of added wheel resistance (which that I expected) puzzled … pulling it back in checking everything over and finding nothing wrong, I tried it the next day. same thing, couldn’t believe how it shook everything again making a terrible noise and making it feel like the trans clutch was slipping and grabbing, but I got it out of garage into the driveway, got it straight, drove forward and then reveres a few times in a straight line everything shaking , causing what felt like clutch slip and grab every time, sounded like right behind front driver tire and I could feel it in the floor board with my feet,... worst right when beginning to let clutch pedal out to engage slightly, shuttering and sounding terrible along the way…I managed to slowly get down the road, babying it the whole way, once I was rolling (out of 1st) seemed to be better and between shifts, then clutch felt closer to normal…not slip/ grab etc., but back down to any stop, straight road or turning, same thing. Made no difference if all tires were straight or if I was turning. All other gauge read out correct. with in 2 miles as planned I reached the empty parking lot and performed the break in procedure that came with lsd, essentially to drive in a figure 8 a bunch.  Did this, binding chattering, and shaking the car the whole way. I drove it back home seemed somewhat normal once I was in straight line and past 10 mph or so, and I know it will “bind” on corners and cause some tires squeal when turning especially from a stop, but when I begin to move it still causes what feels like the trans clutch to slip and jerk badly as well as shaking the entire car, and sounds terrible, that I didn’t expect. I used the fluid they supplied with LSD kit and did the breaking, planning to change fluid as they suggest after breaking, but wondering will it get smoother or less aggressive with use? maybe a 1.5 is just too aggressive for normal road driving?   I have a LSD that I put in my 71 cuda when I restored it, with amazing smooth , quite yet effective results. Different style LSD but that ones a joy to drive. maybe expecting too much from this R200?
