Uprated anti roll bars?

[exdos]

I will be leaving mine stock. Well see how Bedford goes first, but i will install the black powerflex bushes, and go from there. Impressed with the handling as it is though

After driving my heavily modded Z3MC, which I bought OEM, I think the ride and handling of the OEM Z4MC is dreadful, and for less than £3k spent on the right suspension parts, the car can be transformed. For me, it's money well spent.

On the Z3MC I updated both ARBs to H&R and added new Meyer drop links. The difference is like night and day. Well worth the £300-400 investment.

uprated ARBS definately help make the most out of uprated suspension, it's not only roll but it makes the tyres dig in much harder. You can set them up to either increase or decrease under/ oversteer. As Exdos said understeer is also down to how you drive (too hot into a corner the front will wash wide- take a few degrees of steering lock of and the front regains tracktion, you can train brake too for example). Either way you don't want and oversteery car for the road.

Nah Exdos, you just did not give it enough of a honeymoon period. I reckon it takes 2 years to bond with its wikder unruly charms!

My neck simply wouldn't have lasted for 2 years with an OEM Z4MC and I can tolerate karting no problem.

I've just watched it, but what does he prove? He's talking of removing the ARBs and uprating the front spring rates to 1,000 lbs/inch! IIRC the spring rate of the KW Clubsports for the Z4M are around 400 lbs/inch.

Who's talking about the z4m? ? Or running no sway bars on a z4m?

Just thought I'd post up the video on a related subject from a different perspective. Pipe down a little.

Exdos - do you happen to know the rear spring rates for the Z4M clubsports - I believe they're progressive rate?
- I'm running a linear rate on the rear currently and not totally convinced this is right for me, so would be interested to see rates for KW Clubsport progressive
- no worries if you don't, I feel like I've seen them somewhere before, maybe on the US forum?

JimmiVW,

Manufacturers don't seem to like giving conversions of their "progressive" springs, but take a look at this thread: http://www.zpost.com/forums/showthread.php?t=642324 and you'll find the information I think you're looking for.

Much appreciated... When I finally get all my crazy ideas together I'll give you guys an update on my next steps!
