I have a pretty general question about tires, currently my stag is running a set of 215 x 55 Bridgestones on the stock 7j 17" rims, the tires have quite a few screws stuck in them and they make a pretty crap noise when cornering . I have a full set of wet weather TOYO tires that were fitted to my track car, I think these will go really well on the stag. Problem is that the tires are 215 x 40 profile, I was wondering what affect going from 55 to 40 profile will have on my speedo?

Doable or not?

Thanks guys, so if i do this my wheels will be spinning 10.7% faster, so if my speedo says I'm doing 100Kph I'd actually be doing 89Km/hr not including the standard factory over read of about 7Kph.

Maybe I'll give it a miss, don't want to be the slowest thing on the highway!

I find the standard speedo is out by nearly 8km at 100km/h already...wouldn't want to make it worse...

one thing to make sure is that the front and back tyres are all the same diameter & width etc. The AWD system does allow for a minimal difference (ie. to account for uneven tyre wear) but if the difference is too great it will play up.

I'd put them on. Car will handle better. You just need to go by one of those displays at the side of the road that says how fast you are going and then you can calculate what your speedo should read to be doing 109km/hr on the motorway - there's no way you can pull max revs in top gear anyway so your real maximum speed will probably increase (or it would do if you didn't have the 180km/hr speed cut).

You can get a kit from Jaycar to correct your speedo if you need.

LOL my stag is RWD only bud. Keeps me bright eyed and bushy tailed on wet mornings :)

Cheers for the info Kiwi, might check out Jaycar.

might check out Jaycar.

Let me know how you get on with a Jaycar kit if you go that route, I'm keen to recalibrate my speedo also. It seems to read 6-7km/h under at 100km/h. It wouldn't be too bad, but the factory cruise control only goes up to 110km/h, which means 103km/h real, and that sucks :)

VQ25DD,RWD, RX, cruise, navi, HID, but only 16" wheels (wacky size too - 205-65-16)

Just remember to keep it under or over 3% variance

    • So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
    • When you pulled it off, there is no signs of blown head gasket? Is it possible you have some other issues going on? Possible cracked blocked? Or do you think it's straight up lifting the head? Did you check what the head was torqued to before pulling it down (To see if possibly they're stretching, or starting to break threads out etc)?
    • Seems like a decent result for a modded JZX110. They are bulky in comparison to the 100 and 90 models (which I'd prefer myself) but they are getting very few and far between here in JP these days. Thanks for the detailed review and the import process into the UK. I also have a car which I'm hoping to export from Japan at some stage so it's good to know if someone from the UK was interested in it. By the way the corrosion underneath is par for the course for cars which were located in/near the mountains or along the Japan sea coastline. They get huge amounts of snow every winter and the sodium chloride is used on the roads. Many cars have some kind of rubber like treatment underneath but they tend to limit it to the wheel arches underbody and fuel tank. Suspension arms and sub-frames will have similar corrosion to your JZX110 which is a common sight. See it all the time and car dealers here generally don't even mention it unless asked.
    • If the sound goes away when you clutch in, the 1.5/2 way diffs are just shit, and you are a normal person. The diff is likely "fine" but driving at anything under 30kmh is a violent horrible experience. It would be exaggerated with solid diff bushings and subframe bushings if you have those.
