Had a call from Avo today.

My very stiff dampers were confirmed as being valved,................very stiff!

So, they have been valved as standard and I am expecting good things!

Just gotta pick up my refurbed wheels and fit my new tyres.



Looking Great and the air should stay in much better clap

My four dampers were returned from Avo on Friday suitably re-valved to a softer standard setting.

I assembled these with the 80lb springs and fitted them to the car. I then spent a while levelling up all four corners until the car sat level.

I fitted the newly refurbished wheels which look brilliant especially now that they have been shod with a set of Vredestein tyres.

The proof was in the pudding and I took it for a spin. Gone is the kangarooIng from an exceptionally firm damped set up and now the car drives well although surprisingly still firm given the low spring rates that are fitted.

All in all, a positive afternoons work with the weird suspension problem solved.

Very good choice of tyre…Nice sidewall and a more classic tread pattern and fantastic all weather grip.

As Said on a different thread
I thought about buying this car when it was in bits good luck and have fun.
The shocks were sent back to Dg's to be re-valved because they were to hard by a previous owner.
Not me.

Hi Pete. Interested to know anything about the cars past if you could let me know?

I don't know anything before Perry the last owner had it.

The shocks came of my car before it was turned into a race car.
And sold to Perry about a year ago. Perry knows more about the car than me.

All the best

I'm interested in your comment 'I then spent a while levelling up all four corners until the car sat level'

I've spent many evenings on a variety of cars using corner weight gauges to ensure the corner weights are as close as possible. Quite difficult when you sit so close to the rear offside wheel, especially if you're a big bloke. The cars do not sit flat afterwards. I guess it depends whether you want handling or aesthetics when parked.

You'll start considering fuel levels in the tank in a bit Richard….I think levelling up and setting some base settings for a road car is fine…I have never corner weighted my work diesel Passatt!! hehe

Exactly as stated.

When the suspension was fitted the car was very much out of level. I then spent some time adjusting the spring seats of the dampers so that I had 110 mm under the nearside corner plates and about 113 mm under the offside corner plates .

This gave the car a very level look as well as producing a little bit of additional height on the drivers side to allow for my weight in the car when driven solo.

I take your point about corner weighting especially when applied to track car, but for this little car given that I am still experimenting with settings, what I have done is more than adequate and probably better than most cars are set up!

As a habitual track dayer and occasional sprinter I set up my chimaera in exactly the same way.
The car has had four wheel alignment but not corner weighting. It really is a fantastic handling car and whether corner weighting would make any noticeable differance is I believe debatable.

One day, I might.....................

Even though I have had the car both 4 wheel aligned and corner weighted by Mat Smith, the latter with half a tank of fuel and me on board, I still find that it handles best around a race track with a passenger occupying the other seat. scratchchin

Well that is probably because the corner weights are more even with a passenger

As I said it all depends whether you want parked up aesthetics or optimum handling.

If you are happy with what you've done that's fair enough. I wonder how quickly my 1800cc Grantura would see off your Chimaera on track?

If your cars been corner weighted with fuel and driver,,, won't it be out of balance with a passenger, not the other way ?

You may well be right, I just report how it felt. I have only ever spun on track once with a passenger, when the 100 amp fuse had failed and the engine stalled on a downshift just before a tight corner. When I dropped the clutch in with zero revs it was akin to tanking on the handbrake. I have spun on my many times.
I suspect that the extra weight in the car may also have something to do with improving stability.
