I'm looking forward to some track and sprint days. There isn't really much I can do to modify things, maybe fit a custom front bumper and wrap the car to change the colour. Came with black bonnet grille, short stubby aerial, lowered on b12 setup Eibach springs and Bilstein shocks, all black aftermarket headlamp conversion with HID projectors, upgraded front and rear drilled brake disc, recent gearbox,dif and engine oil changes etc, new tyres, new roof motor and upgrade stainless exhaust makes it sound like a V8.

Starting to really like the feel of the Z4 such great handling the grip this thing has in the corners is quite suprising for a RWD car. You just throw the front end round and the rear follows it just gives you great confidence. Had a good day down at Curburough sprint course if only it had LSD.

Went down Shakespeare country raceway put in a time of 14.7s for 1/4 mile. Not bad I thought considering I'd switched back to my heavier 19" beyern alloys from the lighter all black 18" beyern alloys. I just couldn't be bothered to swap them back over the night before. Next time im looking to break into 13s territory with some better starts, less wheel spin and better launch etc

roll on summer

your car handles better than your e46 because it has a decent aftermarket suspension set up if you mess with the camber it will handle worse.

My e46 handled well they had upgraded suspension too one had eibach the other had adjustable coilovers. The Z4 feels like it was built to be a drivers car I wouldn't say that of any of my 3 e46's their more a cruisers car. I'm so glad I didn't buy a big heavy 645i V8 now to replace my e46 330ci convertible always knew it made sense getting the same engine but in a lighter car....more fun, faster & better handling.

just so you know the Z3 rear suspension was taken from the E30 so its two generations older tech than your E46
not nocking your car Gold just giving you some info :thumbsup
I don't have a Z3 its a e85 3.0i Z4 but yeah I read the Z3 had issues with chassis/suspension/sub frame problems only the Z3M is worth mentioning really. The Z4 suspension was actually 2 generations later than the Z3 with better reviews no sub frame issues and stronger chassis. Says in the buyers guide reviews they handle maybe too well it can take away fun of any old style tail happy BMW experience. Which is fine by me as I never drive tail out. It gives me more confidence to happily know the car will go where I want it too. Its lightweight, has real fast acceleration, quick precise steering and sticks to the road like glue.


Wiki "The Z4's design addressed many criticisms of the preceding Z3; the Z4 is larger, and has a significantly stiffer chassis. The Z4 features a strut type front suspension like its predecessor. The rear suspension, however is considerably different from that of the Z3, which was based on that of the E30 BMW 3 Series. Instead of a semi-trailing arm suspension, the Z4 uses a more advanced multi-link suspension.

just to clarify - the Z3 had the same rear suspension as the E30 M3 (WIDELY and correctly IMHO regarded as one of the best handling BMW's ever made) - the front suspension was pure E36. Stock the suspension could be described as 'capable and predictable' - enhancing it with coilovers and a proper set up (strut brace, rose jointed top mounts, solid bushes etc) and a proper corner weighted setup by a professional who knows what they're doing completely transforms the car.. the mistake a lot of people make is that they buy the gear and get a grease monkey to fit it without ever having it setup properly.... or they set it for looks (stance) instead of performance and then moan and whinge that the handling is poor! LOL! - some Z3's suffered from rear diff hanger/boot floor pan issues - but this was fairly easily fixed... and to state that only the Z3M is worth mentioning is just pure ignorance.. ;)

Iv'e never heard anyone compare a Z3 to E30 M3 before. It wasn't just the suspension but mainly, narrow small wheels, the stronger chassis and flared wide body that gave E30 M3 such great handling. Just like the rare bmw Z8 had all E39 M5 bits in a lighter chassis it didn't make it a great drivers car though.

Comparing a Z3 to a Z4 would be like me saying a Z4 roadster compares to a Z4 coupe. The Z3 was let down by with its poor chassis and suspension setup everyone knows that. The Z4 was chassis was designed as it was such a flop Z3 production was ended and bmw started again with a totally new car and chassis. The Z4 was then redesigned further in 2006 with the Z4 coupe and was made even better. Maybe google the design on the Z4 coupe and all about chris bangle's/ andrian van hooydonk's design. I'm sure a lot just see a girls car and don't realise why its that shape and why it has those lines that are angled, flat and twisted all on one plain. Z4 is a decent car so good it's actually bmw's team race car and has been for last 3 years or so and is only being retired for the new M6 car to be used. Google Z4 GT LM you will see it won laguna seca this year coming 1st and 2nd. Z4 will end production this month in August and then we get the all new Z5 with new chassis and engines. The Z3 was never the greatest drivers car it's worth mentioning because of how special the Z3M is being a car that was never intended for sale and was made by some rogue bmw engineers. Who had a plan to fit a roof so did it in secret without permission which ended up being a good idea. Now this leads on to Z4, the roadster was always designed as a roadster from scratch which is why its so good its not a convertible made by cutting a saloon roof off. This again was taking further by redesigning the whole car to make the Z4C E86. Which is why Z4C and Z4MC are up there as the best driving bmw's. The Z4M is the one to collect at the moment before prices sore high like they are now for Z3M at like £25k+. You can buy a E46 m3 with same engine for £6k but doubt you will see a Z4M for less than £12k. Only 12,000 Z4C were built and 4000 Z4MC were built making them very rare and more collectable. Even less Z3M were made hence my reason to say no other Z3 is worth mentioning IMO. Here's some torsion rigidity info which is what made the Z4C handling so great compared to other bmw's

BMW E30 M3 22,000 Nm/deg

BMW E46 Convertible 10,500 Nm/deg
BMW E46 Coupe 18,000 Nm/deg

BMW E46 M3 Coupe 25,000 Nm/deg

Z4 Roadster 14,500 Nm/deg
Z4 Coupe 32,000 Nm/deg
