just change the rear to 24mm marco, the better dampers will control the changed spring rate in roll. Leave the front alone.

The dedra is about 25-26mm(i have not got calipers). Suba, maybe "unstable" is the wrong word to describe toe out,slightly more "nervous" would be a better description, also I think it makes the steering feel lighter,which is not desirable in my mind.

Again, I think this depends on the various mods everyone uses.. If you aim for a full racer Coupe then you'd advice the 24mm+Dedra, if you're the occasional trackday entusiast you'd be happy with the 22mm rear ARB. My 5 cents..

well at the moment the car is used for my fun! i play wsith it nearly every day, enjoy driving it and when i can and its safe push it to the max.
this year i plan to get more track days in.
but i would also like to get it to the stage where i could turn up at TOTB with out worrying my spec is not on point.
i do understand its all down to choice, but luckily, people have been there and done that so im in the best palce to get the right info for one of the best set up's with out spending £2000 on Gaz coil overs!!
for me the best test of this set up will be in spa...

There is no right and wrong answer - how you get the car to behave is down to personal taste.
I would leave the front bar alone for now and go 22mm on the rear - play with the alignment, and if you feel that the front is too sharp, or that there is too much body roll, then go for the front bar as well.

i was expecting an answer like that...
im not going to play with the front bar. The only way i would do that is if i was going to buy the Eibach kit... but i cant afford that at this moment in time.
the problem im also having is getting brilliant advice from well trusted people... BUT some are telling me 22mm some are saying 24mm
all of them can drive and know how to set the coupe up for track and road fun.
and i trust all of them. decisions decisions....
personaly im tempted by the 24mm...
i think i need to kit the suspension first and see what the car... if i feel a minor tweek to the rear then a 22mm will be the key.. but if it needs more work, then of course 24mm and if it still needs it more...
come back and ask you guys what else can i do lol

I'll simplify it for you: 1. 22mm - easy to fit 2. 24mm - pig to fit result: Both will do the job. ![smile smile](/forum/images/graemlins/default/smile.gif)

Nigel, im going for Koni socks and eibach springs! standard shocks are a bit too boring for me!
fitting will not be that bad, i will be doing it on a ramp at my mates garage!
so looks like 24mm will be the better choice of the 2!

so looks like 24mm will be the better choice of the 2! I would say so, but that's only my opinion. My car still understeers with a 23mm rear ARB and a standard front ARB, so if I had my choice again, I'd go for 24mm However, I can get the rear end of my car to step out if I provoke it a little. Because its set up to be neutral, its all very predictable, but if you go too far, it can become unpredictable, which is no fun, and just slows you down, as you've no idea if the car is going to grip and turn, or just spin. You'll be fine with Billies and Konis and a 24mm ARB

You'll never dial out the understeer completely, there is just too much weight in the nose of the car.
You're right about keeping it predictable for road use - I have no doubt that I could drive my old 20VT faster on some B roads than my RX7 - primarily as it was much easier to correct when it started to slip, so you could really go for it.

What is the diameter of the standard 20vt front arb? I found it. Front arb is 23 mm. Rear one is 19 mm.

Quick question:
What size is the standard rear ARB and roughly how much extra strength (springyness/force) does the 22MM provide?
Thanks Look two posts up from yours ^^^
