Space Saver Spare

[LotusGTR]

I've just check this for the first time in 2 years of owning my R as I'm about to go on a long trip. I'm pretty sure its never been out of the boot so I checked the pressure which was 13psi. I pumped it up to 32psi as I couldn't convert 4.2kgs/cmsq to psi on the spot (the rest is in Japanese so I'm presuming this is a max or recommended pressure) so thought I stop there. When I got to the office I came up with 4.2 kgs/cmsq = 59psi which sounds very high.....

So my question is a) can someone confirm that 4.2 is 59 and b) that this sounds right? At 32psi the thing bounces like a like a rock........

Thanks.

yeah they carry a heavy load thru a small area, so the prssure is much higher than normal

yeah 60psi is right for the spave savers. wear goggles when inflating! haha.

also when your ap's brakes are on you'll need to toss the space saver in the bin and pray you never get a puncture.

all i know is that i'm gonna pump up two space savers to 60psi, stick them on my brothers r33 and smoke 'em, should be fine

Yep. I've sourced a 5th R34 GTR wheel and will have something fabricated to hold it down in the boot recess as best as possible. Oh the joys of modifying cars.

don't space savers sit out from the brakes? (ie offset) if not i should probably turf mine too.

[Duncan]

yeah they will clear the standard front brakes (have a very funny shape to do so).

but realisticly, even if you have changed your front brakes you can still use it on the rear - so if you are unlucky and get a flat front put the back wheel on the front and the space saver on the back. and pull the 4wd fuse under the bonnet if applicable

i got r33 brembo's on the rear, and porsche 355mm on the front... so i should probably turf it. And hope i'm not down the west coast of tassie
