the misses has gone and got a puncher and drove 5 miles with tyre flat ,
i know what a stupid bitch
if she has damaged the wheel ,which i think she may have ,can i put 17 inch wheels on the back and keep 18 on the front ?
i dont think it should be done

 

You can but the bill will be much more than that for an alloy wheel and tyre

 

I think it is illegal to have different sized wheels mate

 

Noooooooooooooooooooooo...

 

The issue with having different sized wheels is that the rolling circumference of the tyres will most definitely be different and your center diff will overheat and fail due to trying to get the front and back wheels to rotate at the same speed.

If you want, you can do the calculations and put different sized wheels while having the same rolling circumference tyres, but for the time spent and cost of tires, it would be easier to simply put 17s or 18s on all 4 corners.

 

no lots of cars have bigger back wheels,
i have a set of the 17 wrx wheels out back which are 215/45/17
see has damaged the front left,if i put one from the back up front cos of brembos and put the 17s on rear to get home 8 miles will that be ok,and not damage diff

 

yeah i thought that would be the case saiklon,
going into see the damage fingers crossed see has not smashed wheel

 

For 8 miles you will be fine. After all the spare is much smaller than that and causes no damage for short periods of time. I thought you wanted to use 17/18s as a long term solution

 

Nope not illegal at all, there are a hand full of cars that have bigger wheels at the back and smaller at the front (think hot rods and what not )

Usually spare wheels are around a 13/14 inch, if it was illegal to have different wheels we wouldn't be able to use spare wheels

If its a 2 wheel drive car, you can do this, as long as the wheels are the same "across the axle" but do not try this on a 4 wheel drive, as stated before, it will kill the diff trying to keep the speed the same

 

I think their is a Spare fuse in the engine bay fuse box which when put in the correct place disables the rear diff and makes car front wheel drive only well thats what i read about my 04 wrx

 

Really has gone to the dogs regarding technical advice in here these days.

BTW wich dumpvalve should I go 4?

 

My mate Danny az got a mate who knows sumwun who rekons the lowder the valve the betta the performase, lyk 100brake or sumfin

 

 

Deary me, where do these myths originate?

 

That was an epic quote.

 

, Not on your car matey i'am afraid ,if you buy a impreza that is automatic and non turbo then there is a fuse holder near the drivers side bulk head that if you insert a fuse it makes the car FWD,however if you have a impreza/legacy automatic with a turbo,then the inserting a fuse into the fuse holder locks the centre diff giving 50/50 split which is great for when driving on ice or gravel,but not recommended for normal road use or tarmac..

 

Are you sure it's a WRX you're driving and not a Vauxhall?

 

As said earlier subaru do fit such a device on there auto non turbo models,but not on wrx/sti models.
