Autopista style rear wing is on.


 
Very unhappy with the Gen3 Front Lip.. With all due respect to everyone's opinions and preferences, as an outdated and expensive 2nd hand item, it's a waste of money IMO comparing to brand new aftermarket bumpers and PU lips that I could've got for the same $.. 
I did the installation with the bumper on which is doeable but obviously uncomfortable (especially when you're dealing with 25 years old rusted and corroded screws).
The lip simply does NOT fit on the gen1 bumper. it doesn't sit "comfortably" with the bumper. The existing holes don't line up nicely.. I did some research, and some people have drilled new holes in the bottom of the bumper to make it fit. The only problem is, even if I make it line up and sit properly, it will be under constant considerable amount of stress (bending force), and it will snap/crack in no time.. It's currently sitting with its front looks like it's pushed back (hanging on tight to the bumper, so no safety issues there)
 
The only reason I left it on was hoping it can help me for the upcoming track day in 10 days. It's coming right off after that!!

I assume you don't have the extra parts that are used on the later models that go with the later lip. 
I found that trying to fit the later lip to an early model is a waste of time without them, lol.
 
Extra expense of course, but there are about about 5 or 6 specially shaped reinforcement plates with captive bolts, and this makes the whole assembly fairly rigid.
With the plates I got mine to line up nicely with my original bumper with no probs, and no drilling needed.
 
The part nos should be cataloged somewhere, and I think I got mine from Litha Toyota for the best price.

I do have all the 6 plates needed.
The shape/curve of the lip simply does not line up with the curve of the bumper full stop (I quad-checked today).
Regardless of plates, holes, or screws, if the curves don't match, the lip (or the bumper) will be under constant stress once they're installed flush, which is a big no no, they'll snap on the track in no time.
Maybe the shape of my bumper (or lip) that I have is distorted for whatever reason.

As of last night, the car is finally at an "acceptable" point where it will be at the 16 Nov Mallala track day.
 
I have only one stock rad fan mounted onto the Mishimoto Radiator.. I had to slightly modifiy it to get it on.. the other fan was a lot more stubborn, so I gave up on it knowing I will be receiving the Mishimoto Fan Shroud next week.. too bad I wont get it in time for the track day :(  but I can easily mitigate that risk.
 
Bleeding the air out of the cooling sytem wasnt "hard", but bloody time consuming to be honest.. I finally took the car out around the block for a "spirited" drive, and the temp gauge stayed where it should.
 
The current car's presentation and cosmetics are in an average state.. but no time means lowest priority..
 
I didnt get a chance to work on desirables such as cameras etc, but should have something going for the MTC. Cage only looks nice from a distance where you can't see my embarassing paint job :)

Today was a success on the cooling front. Hot day, but the temp stayed where it should.
 
I wasn't aiming for any PB as it was more of a testing session.
 
Lack of time (preparing to move interstate!) meant I went out there with few systems (brakes, suspension, cooling, front Aero) in a below average shape..
 
- The front rotors were getting the "shakes" big time, which resulted in my brakes feeling no where near as good as last time..
 
- The chassis post roll cage felt nice and rigid, but no proper suspension adjustment and wheel alignment to suit the "new chassis" meant the car felt unstable, like it wants to hop and dance.. Really twitchy.. 
 
- Front Aero (with the Gen3 lip that's not sitting 100%) is better than last time, but obviously could be improved. I wouldn't say it was a major limitation today, but definitely on the table.

And apparently I did 1:23 again according to the results today.. I didn't "feel" fast at all TBH, which tells me how much potential the car still has..

Great to you have the car turning some laps.
Soften up the shocks will help settle the car. disconnect the rear sway bar if its still moving around too much.
A 1.23 is a stout time. That will see you under the 1.10 at Wakefield in Jan!

Thanks mate, I might try that.
 
Today I visited a suspension shop that helped me with a good alignment, suspension setup and height drop. few things were way out, which explained why the car was unstable on the track the other day.
I need to raise the rear a little, as the rear right tyre is rubbing on the wheel arch when I hit nasty bumps unfortunately..
 
Upon further testing, one of my problems was the uncommanded steering input during the lift-off weight transfer (from the back to the front), which obviously is an issue that's a lot more evident with roll caged chassis.
This is now rectified but yet to be tested on the track.
 
Conclusion: Suspension setup is black magic and I have a long way to go
