i have a 1990 import tt auto which im having a love hate relationship.

it is fitted with a set of bk146 wheels...215/45 17 on the front and 235/45/17

on the rear, bk racing have told me that the rear rim is only 7" and with the 235 tyre fitted is wrong...what are the correct size wheels...as the handling on the car is appaling.

on a smooth road every is ok, but hit any bump or ripple and the car feels like its moving sideways (which it is )....i have replaced the hicas steering arms which improved things but still its bad. i have had the 4ws alignment set up also.....could the wheels be the problem...as i dont want to buy new ones and find out that there are not the cause.

also the heater does not work, since my local garage replaced the radiator,and they dont want to know, and now the passenger electric window has packed up, but im advised power is getting to it.

does anybody know anyone near ish to where i live conningsby lincolnshire

(20 miles south of lincoln) who knows these cars and could restore my faith in these cars and fix this for me.....help! desperate tt owner...carl

With regards to your handling prob. Not meaning to touch the obvious here but are you sure it's not your rear suspension u/s. I had one of mine start to leak oil and the handling went almost immediately. Hit a bump at speed and she bounced all over the shop and handling round corners was appalling. Push down on the back end - if it bounces its shot. I bought two new ones from the Z centre for about £70 all in.

If you have too wide a tyre for a wheel, it will bulge out, causing you to only drive on the bulged out part of the tyre. I would say that only a 1/4 of the tyre would be in contact with the road and it will wear down your tyres a lot.

 

I think 7 inch wide wheels are meant for 215 at the most, and having 215 on a 300bhp rear wheel drive car is stupid.

 

Are you sure the engine water is getting to temperature? I presume you know how to work the controls then?

 

the drivers side electric window switch has a button at the top of the controls. Have you tried pressing this as it disables the passenger window.

i know what button you mean...no its not the lock button on the drivers side.

the water is getting to temp...guage goes to normal and i have tried to bleed any air out the systems as well...but there seems to be no air pockets.

the car came with the wheels, so i suppose if i could borrow or get a very very cheap set of std wheels to put on and try this would rule out or in, the problem.

im deperate to find somewhere/someone who knows these cars and can fix this problem...who is not 100 miles away.....love the car....but patience is almost gone now..... thanks for your advise

I would say most of your hadleing problem is the tyre size.

Standard UK tyres are 225 front and 245 on the rear.

7" wheels on a Z would be like driving a pram with gears

Should be 8.5" front and either 9.5" or 10" rears

Arent standard 8 fronts and 8.5 rears?

According to my owners manual, standard fitment is 16 x 7.5 (front) and 16 x 8.5 (Rear). Tyres would be 225/50 16 (Front) 225/50 or 245/45 16 (rear). It would sound like your wheels are too small. You could easily buy a second hand set (original fitment) off of this forum or try ebay. They are normally very cheap (even with tyres).

cheers guys....appreciate the advise...ill get a set of shockers oderded off

jeff at zed world...as they are only 70squid a pair...that would wipe out one potential problem...and it looks like i need to get another set of alloys.

i have spoken to mark at zen garage...so hopefully he will have an idea or2

as well....looks like the heater matrix valve could be the fault as after speaking with jeff , he told me to check the 2 pipes going into the bulkhead.

it would seem only 1 of them is getting hot...(mark another job for you im afraid as i havent the knowledge to takcle this one )...ill keep me eyes peeled

for a set of alloys.........thanks everyone.....
