Thanks for the advice about the suspension, it has just kicked me in my big butt to remind me that it is what I should look at. Having driven numerous times along the old pacific highway where it more a bumpy goat track than a "highway", I did notice the weak damping on the 8. The 8's suspension is a fantastic compromise as most of you have said. Comfortable and yet controlled even in spirited driving. It's limitation only shows when pushed to 9-10/10ths ie on the race track.
Could you tell me what mods you made to your suspension setup?
Thanks.

How did you arrive at compression and rebound settings before installation or is there access to the adjusters?
Thanks.

does anyone remember those Audi TT flip incidents? they recalled them and fitted a little "kick up" rear spoiler to get more downforce....... i quite like the style of the spoiler :p

Was it at Eastern Creek?
People have mixed report from Koni, it is very personal and most reports are touch and go. You like it previously, you will stick with it; if you don't, you stay away. It is very hard to say, though, one product for a particular car will transfer to experience in the RX-8.

From my research it was recommended that the rear has an optimum setting that works really well on track or the road. Go too hard on the 8's rear and it gets twitchy. I applied the recommended setting of one full turn at the rear and I must say it feels spot on. The settings for the rear has come from guys who are tracking 8's and have lots of experience setting up circuit cars. For the 3 tracks they use and the drive to and from the track they found they only needed to play with the front adjustments and still run times equivelant to full coilover setups. Set a bit softer for a nicer drive to the circuit and then up the setting depending on the smoothness of the circuit.
I have so far found the harder I set the front the quicker the turn in I get but if it gets bumpy while on a harder setting the front end gets loose.

If you have the money a full coilover setup will provide more options to play and give you the full 10/10ths not just the 9/10ths this koni setup gives, but at half the price for me it was the better deal and with the savings I was able to buy a set of Toyo R888 semislicks for the track :D The other thing you need to know with most coilovers is that they can be susceptable to corosion as they have a fair amount of working parts exposed. The koni's are fully enclosed and have a lifetime warranty and are not like the koni's you get for some cars which are just inserts that get put into the stock units. These are full replacement units!
Man I can babble on.... Sorry, I am just so excited by how they have made the car drive! I'm a big kid with a new toy :D :D :D

Back off on the Volvo thing! ![Mad](https://www.rx8club.com/images/smilies/mad.gif)
I had Konis on my 740 turbo wagon. You do know this car ran competitively in the Euro touring car series, in the late 80's :o :o

Thanks for the advice and info.
For my application I think the Konis would be better value as I'll only be doing a few track days a year. It looks like you're happy with the guys who did the work for you. Would you send me their details?

I did a little more research on the whole rear spoiler /downforce /extra drag thing. Here is what I found:
In a straight line, extra downforce is not really required (at least at the speeds we can drive an RX-8 at). Going fast is all about minimum drag, and a wing creates extra drag which is counterproductive to top speed and fuel consumption.
In cornering, the extra downforce will increase traction by pushing the rear of the car into the road harder. So there is a benefit on the track in having a rear spoiler /wing.
For me, I'm going to keep the back end clean. As an aside, the European lip spoiler is said to decrease the RX-8's coefficient of drag from 0.31 to 0.30. Pity we can't get them here though.

I've also decided to keep the back of the car clean. I prefer it that way aesthetically and figure that if I ever use it for track work on an extensive basis (unlikely) the first thing I'll attack is the suspension set-up.
Not knocking those with wings BTW.

There is nothing wrong stability wise with these cars.I'd be checking wheel alignments and tyre pressures.
It ain't the car.

Front -1Deg -ve camber, Caster L+8Deg / R+7Deg 30', 3mm Toe Out. Rear -2Deg 15'-ve camber, 1Deg 5' Toe In. Strange that on my car you couldn't get more than -1deg on the front!
Running 34/34PSI at Wakefield, the 8 still understeered although it was a lot more stable. The rear didn't break loose as before. Dropped the front to 32PSI and it was better. Ended up dropping it to 30PSI for the last session and it was sweet. The rear tracked and the front tracked true. Understeer can still be induced but that's just my crappy driving. Gotta learn fr you guys. Next time you and Rod go for a practice day, can I tag along?
