Well....
You could change all your standard components, that makes a massive difference!
Or
Standard shocks with eibach springs
Or
Up rated shocks with standard springs
What do you want to achieve from doing this?

Hi all, looking for a 50/50 mix between comfort and improved handling.
Any advice welcomed. A set of Eibach anti-roll bars, polyurethane bushed wishbones and new standard dampers and springs all round. That will give you standard comfort, less body roll and more precise steering.

I'd say make sure all you basics are sorted first; Wishbones, bushes, top mounts, droplinks,tracking etc. Good tyres are a must. Then ; (In my order of preference) Top brace Lower brace Good shocks (Osravs on mine) Uprated rear arb (whiteline 22 on mine) Camber bolts. Add into the mix uprated springs if your ok with the ride. I'm just about to fit some to see if i can live with them. Plus I'd say for "real world" on road pace Good Brakes should not be overlooked. Happy days

Looking at your profile it looks like you've got a 97 20vt which didn't have top strut brace as standard. Check if one has been fitted already. If not, this cheap first step will suprise you with it's effect. Back it up with one of Nigels lower braces and you'll have great improvements for little money.
P.S my list was fitted over time (not all at once) as my wife funds allowed.

But the greatest effect will come from the classic Eibach/Bilstein combo. (and remember to cut the bumpstops!  )

like Jimbo and sandytim etc said:
For comfort/performance i would check all wishbones,drop links,topmonts std springs etc are in good order/replaced. Then add: bilstien dampers/osrav dampers. front and rear anti roll bars. lower and upper strut braces. camber bolts.(1 deg negative)

Is that to do with the lower eibachs? Only partly - any amount of lowering will increase camber slightly, but on the Coupe its minimal, because the wishbone is close to horizontal as standard However, when I had the Koni front shocks, I needed camber bolts to get the camber to more than minus 1 degree, so it can't be all down to the lowering I reckon its because the hub mounting holes on the Osravs are very slightly different

I can only "just" get negative camber with camber bolts on the gaz struts.

I am using the supplied increased caster topmounts,maybe its just my camber bolts? Barbz is going to slot my dampers and use a adjustable washer to give me more camber.

Just a point worth noting - Osravs appear to produce negative camber without camber bolts - my car is showing around -1.25 degrees with the standard bolts That's a good point, right? Negative camber 1-2° sharpens the steering, at the expense of straight line stability, and tyre wear?

Standard camber is -0.5 degrees - you might want to try elongating the top slots or perhaps going for custom top mounts This method is good and free to DIY. FK's and KW coilovers come with an elongated top strut hole. Just ensure you use a decent lock nut to tighten the top bolt.

D2 Coilovers.... think there is about 30 odd different comfort/stiffness settings.
Best coilover setup i've saw in a while too!!

Apologise in hijacking this thread, but i am looking at refreshing the suspension too, and one of my main concerns is straight line stability as mentioned further up the thread being the reason why i am doing this.
My car becomes light and a tad twitchey - feels like the car is not touching the road when going round a slight bend on say a motorway around speeds of 90mph (on roads that allow) I am pretty confident it is a standard setup, Can i ask what would cause this? and what i would need to do to combat this / how to diagonose?
Again very sorry Hoban but your answers would be much appreciated!
Many Thanks
Mick

Poor alignment and worn top mounts / drop links / track rod ends / worn dampers / springs / poor tyres.
Unless you are hooning it round the corners that you mention then the standard setup if in good condition should not feel the way that you describe.

Check your rear trailing arm bearings,they can cause the above symptoms when worn.

good shout - forgot that. if you get the alignment checked and you have excessive rear camber, then they will need to be re-built or replaced.

I replaced everything on my suspension bar the rear springs for standard parts. CAr now feels well planted even on the M3 M25 slip road bend. Oh - that nice little bit of road that is good for testing setups!
