    I'm leaving that up to camber-Ken @ Accurate. He's set up a few of these now. Once I get a few laps under my belt with this car I'll be able to give him some feedback as to what it's doing and go from there.

    Ended up with -4 front, -3 rear, 6 degrees of castor on the front 0 toe, slight toe in rear. Yet to drive it. He's kept it at the ride heights above.

    Spring rates are currently 8kg front and 6 rear, may end up being on the soft side. Once I know the car a lot more may end up with 10 front and 8 rear.

    Pretty sure all the MX5 boys like it harder in the rear end.

    Those figures look familiar. With the motion ratio of the suspension, the front springs generally end up with a higher rate. From memory I ran 6/5 on a my last NB which was a really nice place for road based tyres. -4deg is certainly the higher end of where I would be unless it was slick shod with decent chassis and body strengthening in which case more was nicer. Mind you, my info is a bit old now and I also always chased wheel travel (esp on droop) over neg camber or lowness.

    Might get myself another MX5 after reading all this.

    Well it drives far nicer than expected. Really doesnít feel that much firmer than standard. Certainly donít need a kidney belt. There was some rubbing on the RHF guard. I removed the liners the other night but kept the splash guards in front of the wheels. Looks like it was rubbing there, a Xmas tree plug was broken and hanging and must have been grabbing the tyre on light lock. Have removed the splash guards now too.

    If anything it feels a little soft, I havenít played with dampener settings yet and will reserve judgement until giving it the full rissole on the track.

    8/6 is quite soft on the track and very easy to live with on the street.

    Ive gone to 11/7 and its better on the track and still fine, if firm on the street with the dampers backed off. Will be going to 8 kg rears soon though give a more neutral balance.

    -4 is a lot of camber.. I've only run - 2.5 with my elbjs and the camber wear on my PS3 street is noticeable after 4000km, and tge are ready for the bin (so are the rears but for different reasons... ) but I do drive it hardm.

    Yeah, Ken's always loved his camber. Interestingly there's a well known turbo 2B car up here he sets up, runs -4.25 on the rear!

    I imagine there's more than one way to skin a cat and everything needs to be taken into context. Just in here we have vastly different set ups used/recommended. But he's got the runs on the board and I've been using him for nearly 20 years now.

    I'm also under no illusion that things won't be changed up a bit, but at the same time I haven't even belted it on the track yet, so I'm not even at the "trying to drive it quickly, being uncomfortable, gaining comfort, dropping time, understanding what needs to be changed" bit yet.

    Oh, the new intake also sounds awesome at 6-7k!

    Cal last week "you need all the camber". Cal this week "I only run 3".

    This isn't a daily driver, it will drive from home to track. I gave the instruction that daily driven tyre wear is not a primary concern when setting up the alignment.

    Yep, they're fitted, hence the -4.

    You sent it before you said you need all the camber. If I'm woefully slow next weekend, it won't be because of the wheel alignment.
    I'm actually looking forward to giving a car 12/10ths again without fear of one of 11ty parts potentially not being up to the job.

    Will be good to hear how you go. Do you have a pyro to take tyre temps, or are you just going to keep an eye on how the tyres wear?

    I think I do have one somewhere. I reckon I'll just keep an eye on where this weekend.

    I'm trailering it up too, as while the purpose is to have a car to drive to the track and back, unfortunately I can't fit a swag, tools and kit in a clown car. So at least I shouldn't be putting an un-needed 400 road kms on this rubber. They're pretty bloody soft.

    Yeah, what Bren said, that's quitter talk.

    I used to fit the four track wheels with R888's a trolley jack, my race kit, and a tool box in my NA6 for track days.

    If you need to take a passenger, well that's a different story....

    Good point re passenger, that changes things. I didn't even have the passenger seat in my car when I did it

    Like everyone else that seems like a crap ton of camber.

    Off the top of my head and it been a very long time the go to suspension spec for a road/track setup was:

    1-1.5 neg camber all around
    0 Toe Front
    1-1.5 mm Toe In Rear
    And as much castor as it'll take, typically 5 degrees though I remember Edo saying that he managed to get 7 degrees into his with I guess a lot of patients.

    Me being a 20-something year old idiot got 1mm Toe out in rear which wasn't a good idea especially with old tyres on the rear at Morgan Park, was super taily and cost bulk time.

    I've not been happy with my setup for some time--not enough grip and too taily, and I know your thing is well set up and you can drive a bit
