Have not had any front end issues only reason for that would be a lack of adjustment on the standard setup from what I can gather. With the coilovers and 4deg neg camber on the front + 5 mm castor and 2 deg toe out had no problem with under steer at wakefield or eastern creek. Main issue is with the rear as it becomes twitchy at high speed as if it wants to step out and also out of cnr's not having a lsd it likes fry the inside. My car will be going to these guy's in Jan for a complete setup and test day to see if any improvement.

I had the front end comment mixed up with someone else. I checked the link you provided and didnt stop reading until I had read everything on the site.What a great read.Thankyou for the link.
It will be the beat value for money you will spend on your car(in my opinion) for real performance gains to any car on road or track. After I have finished the chassis it will be my first port of call. Suspension tuning.

Im sure your issues with the car being nervous in high speed corners will be overcome after your car has been returned from the suspension tuners.

cheers

Steve

Sounds like a competitive package with up to 280kw.
What brakes are you running and are you runnning brake bias?
Have you added chassis braces?
Are you planning on racing the car?
It can be run in super TT on the 1st of Feb at Wakefield Park along with the Wakefield 300 in November. Im looking at organising a 300km race for EC in 2009. You car will also be eligible for this event.

Hi mate and happy new year to all
Brakes on the car are 330mm G4 8 piston calipers with Cryoed Disc's up front and 280mm standard on the rear Yes have now fitted a brake bias as the fronts were locking up. Car is being setup for Dutton Rallies and super sprints around NSW with a view to doing Mt Buller hill climb and Drive Bathurst in late November. As for the wakefield 300 may be a starter as steve in the red rx7 Dared me to do it last Year but car was not ready and as i would like it.
Power is the easy part of the whole equation but it must be done reliably which is why we need to gather Data. Turbo is the same as is used by the rally team TRD a ct26 which spools up to full boost at 3500rpm and keeps producing till 7800rpm + and makes the whole package very responsive at 18psi. cams and headwork have been done to 1 head and a standard head with just polish will be used for Mt Buller hill climb if it is required to be standard. Am investigating Carbon doors and and lexan if anyone is interested in a group buy

I may be interested later in the year re: the cf doors but Im just focused on majors to get the car on the track at the moment.
Im happy to lend a hand at the track if required.
Here is a link to an ex MR2 production car. Its worth it just for the chassis and suspension package.And if its the one which Jaune Fangio II drove in the BAthurst 12 hr with a 4th outright finish, it also has some fine history.

Has anyone gone around QLD Raceway? I went on an Evo suicide run a couple of weeks ago up the north coast and these guys were psycho fast. Two of them track their cars at the raceway often enough to be running 1:01's so I'm wondering if the MR2's can match these sort of times?

I dont know for certain if MR2's will match their times. The reason for this thread is to see what people are gettting from their MR2's based on the mod's they have made.The MR2 does have the potential to be as quick if not quicker than most. I think MR2 drivers enjoy the experience of driving a Mid engine car more so than being at the top of the list.Maybe..

I guess it depends on how far people are willing to go with money and time in not just the build but the development of the car. As I stated at one stage "MR2 won there class in almost every endurance race they raced in". These car were restricted and with only a NA motor. SO they have potential.

A unrestricted MR2 with at least the following:fully seam welded, comprehensive cage, widened track, 38-40" of tread on the road, the right suspension package,1050kg + 230+RWKW plus some quality driver training and you will be up there.
Cost....I will let you know when its finished.

Thats my humble opinion based on what I have seen so far.

I have been talking to the owner of a Production sports Sb MR2.
Naturally aspirated 93rwkw
1160kg
Proflex dampers
Std brakes
cage
Times: Eastern Creek 1.53 on used yokohama's, 1.50 on slicks.

Its a coupe with all the running gear from the 2002 Bathurst 24hr(B24) MR2.
He also stated the TT is 60kg heavier than the coupe! Damn..

Was talking to Dale at race car tech about my car and mentioned that as the setup is, the car needs roll center adjusters but he also mentioned that at the rear he need's to strengthen the toe adjusters as they have way to much flex and moves the toe to a +2-3 deg on compression. I thought this problem was rectified on the series 2 and 3 but obviously not so will post up pic's once the mod is complete

I think the toe adjusters have been modified on my car. I will take a pick and put it online for a comparison with your system.
Will be interesting to see what they( race tech) come up with for the set up for the car plus what difference it makes. I supect it will behave very well after this tune.
