What settings are best suited to very extreme fast road use when fitted with Gaz Gold Coilovers ive got them on my gti6 engined 205 at the moment on 14 clicks up from full anticlockwise with the back shocks on 4 just took it out on its first run feels very bouncy at the front but ok ish from the back im running with 275 lbs springs on front.The ride height is equal front and back but im not happy about this bouncing about from the front any suggestions on how to stop the bouncing ?

low frequency bobbing


Dont you need slightly stiffer springs and damper setting then in that case?

Standard suspension with softer springs and damping did not do this considering these are much harder than standard dont know whether this would work.They run 300lbs plus springs for track cars so i think 275 should be ok for extreme fast road use.Ill go stiffer a couple of clicks to see if it solves my issue .

Figure out your corner weights and wheel frequencies first.

Sounds oversprung and possibly overdamped, the above will tell you a lot.

Are you sure it's not the rear oscillating and causing a slight bobbing feel from the front? My dampers are set up differently from a standard Gaz, but I usually run 14R/10F, or around there, depends on the weather.

The other thing is, what spring rate (tb size?) are you running at the back?

Im running standad size tb 21mm i have now turned down all the dampers to zero the bobbing has impoved a lot but is still there much better ride quality over pot holes etc than standard but still get the bobbing than i never got with standard suspension.What ibs springs have you got on the front and tb,s at the rear ?

Corner weights can be obtained by putting it on a corner weighting machine (basically four plates that weigh each corner). Or you can get a percentage front to rear weight from a MOT brake tester if you know the overall weight. Ideally with the normal kit, say half a tank of fuel and yourself in it.

Have a google search on wheel frequency calculators and go from there.

One thing these cars need is very good rear damping as it has to do a huge amount of work due to the angle. Do you find it gets worse as you drive it more?

I'd ecpect it to pitch a little over undulations with those spring/tb rates tbh, the rear will never react fast enoiugh to match the front

What would you recommend 21 mm tb's ? More poundage front springs 350 lbs?

Probably needs more rear bar, although it's not often something people notice apart from long undulations.

It'll ride pretty rough, but if you crank the rear dampers up to 12-14, does it reduce it or make it worse?

Regards to rear tb's do gti6/xasra vts tb's fit standard 205 rear beam ?If fitted 21mm tb's to my 205 and provided i get my damper settings spot on does the car sit level or does the back sit lower than the front or vice versa seem to be getting mixed opnions on this what is your take on this ?
With standard rear beam and 19 mm tb's how should the car sit lower at back or front or level ?

Entirely depends on how worn the beam is and how much weight there is in the back of the car.
You want a bit of rake towards the front and also look into upgrading your rear arb.

Its getting better now that i have lowered the front end more the bobbing effect is less.It seems like it was a case of bringing the front end lower to shift the balance more to the front.Now its just about finding the right settings to suit my personal requirements.Although i am open to suggestions

"Buy some good quality coilovers, sorry any company that call there's product Shock's don't fare well in my book". Semantics and snobbery. I know this is a long time ago, but I still think Gaz get a hard time, when they do a good job for the moneySmile
