Uprated Anti Roll Sway bars

[UnicornM]

Anyone looked into this?

I believe some, maybe all E70s have option of Active roll bar?

I came across this company offering some chassis stiffening items for the E70 - http://www.ultraracing.lv/?lang=en&m....0%2006s1rma1s

Even with KWv3s installed I wonder how much more out there is on offer in terms of chassis tweaks.

Buying parts from Latvia? Hmm, want to make $10,000 a week working from home too?

That said, I like the idea of bracing, I haven't really felt a need for swaybars, even stock. The car is actually setup well from the factory with the OE bars IMO

Sure would be nice if some other tuning companies hop'd on this one, but seems choices are rather slim other than this Latvian brand. In the UK I certainly feel the need for less roll, wondered if anyone had any thoughts

Stiffer springs prevent roll, and with the right spring rate, swaybars are not needed....

A little roll is not a bad thing too.

Sure, 22s and KWv3s have improved things already. Though the lack of initial turn in and oversteer is something I want to get rid of. I've not tried too many settings over KWs recommended rebound and bump, but perhaps if someone has any recommendations I can give it a tweak.

The 22's have probably affected the turn in due to the high rotating mass. But you can minimize that a bit.

You can play with tire pressure, less in the rear by about 2psi to reduce oversteer. Camber up front is adjustable, so you may want to make sure you have around -1.5 to -2.0, the rears, I don't think are adjustable.

Lastly you can change the rake of the car a bit too, but you'll have to get a new alignment.

Technically there is an "ideal," setting for compression/rebound on a coilover based on the spring rate. Too high or low you get bouncy or wavy/oscillating like characteristics. People that say they "stiffened," their coilover for the track and back for the street are doing it wrong. :-P

Camber on the front of e70 is adjustable?

I was under the impression that there are 2 available fixed camber arms and they only change the camber by 0.1 degree.

Is there a fully adjustable camber arm that i have been missing all these years?

AFAIK there are 3 different camber arms, 0.5 deg difference between each.
