    Viewing a Z4 today!

    See how old the tyres are... could be ancient if it only does 800 miles a year.

    What Revs for fuel efficiency?

    Lowest ive ever had was 13mpg on a trackday at spa. No idea what the highest was!

    Track Questions

    Get a tyre pressure gauge for a few dollars, then you can check and bleed off pressure when the tyres get hot after a session on track. I'd guess in californian sun the pressure will go up by 6-8psi, which will then make the tyres slide around a lot more. Also those pads look fairly standard...

    Track Questions

    My guess is your spelling of tires, and use of rotors suggests you're stateside? I know tyrereviews just did a great review of 200trw tyres, so id start there. However... id do a few days on the mps4s to get a feel for the car before moving to stickier rubber. If you dont slide around, keep an...

    High mileage ok?

    My e85 3.0i was happily pounding round racetracks with 150k on the clock. Only thing that went wrong was an alternator. Id likely try and get some service history, but the 6 cylinders are pretty solid. Id probably go for tidy car with high miles. Are you able to service it yourself? If yes...

    Odd handling at speed

    Are the straight roads dual carriageways, or see a lot of heavy goods vehicles? My guess is the very stiff sidewall front tyres are tramlining in lorry grooves, but the soft sidewalls rears are being affected less. If the fronts are relatively new you should be able to sell them to help fund...

    Odd handling at speed

    And ending point. Get those run flats off immediately. Currently your front axle is sniffing out all minor surface imperfections and following them, while the rears are just staying their course.

    Using car without strut braces. Ok or not OK?

    What are the apparent torque specs for a strut brace, out of interest? The size of the socket needed to do it up will also give a clue towards the torque. Don't read too much into the inaccuracy of a torque wrench comment - even the most expensive wrenches won't be 100% accurate, all will be...

    To sell or not to sell....that is the question

    Time to get rid. If youve had the enjoyment of building it, its got you into the classic car scene, and someone's already offered you good money for it (?) Then move it on now while in season and buy the next thing. Unlike wives, cars don't mind being traded in when you fancy a change for a...

    17 Inch CSL wheels Will they fit?

    Use willtheyfit to see how far out they'll sit compared to what's on there now. But yeah, does sound quite aggressive.

    How long is "Lifetime"

    I thought lifetime for bmw meant 100k. But... if you want to keep it past 100k, it might be prudent to change it. I think the gearbox manufacturer recommends changing it too.

    FOR SALE Valencia Orange Z4 E89, 18i 2015 for sale - Reduced to £6000

    Is there really no other way? Me and my wife very rarely need two cars, but we have two anyways, because i want two cars - one practical, economical auto, and one sporty, 2 seater manual. Given how long its taken to get your license back, and get a z4, seems a real shame to sell it so quickly...

    Z4 Ride

    First thing to check is for run flat tyres, if you have them, swap them out for conventional ones ASAP. Secondly, a lot of bmws of this era are very stiffly sprung, but under damped, resulting in a very harsh ride. Solution would be some aftermarket decent springs and dampers - not necessarily...
