It is very difficult to beat the Eibach/Koni combo. There is some tradeOff due to the Progressive ,but I remember the days when I took my car with this setup on long road trips - true GT car.

Got quite a few tasks done in the last 3 weeks. Installed Engine: Bored ATI damper and installed it: Found some rust at the welding points of the cage ,and the racing seat rails. Spend a lot of time sandblasting ,priming , sealing and finally painting with stone guard...

More caster heavily affects the dynamically induced camber on some suspension geometries. My experience (DSP 400 ; MA70 with 2inch front drop) - at 10 degrees turn I only gained 0.2degrees of camber for 3 degrees of caster. That is way too little ,in other words if you have to trade between...

Got some progress this weekend. Removed the TKO subFrame and installed the subFrame from the LDZ supra. Using JZA70 / Cusco diff build by Antonov Transmissions :thumbup:. This begin the 3th time I'm swapping subFrames ,took me less than 30 minutes to take the old subFrame out! Installation...

You are correct - the power loss was probably significant ,not to mention cyl to cyl deviations and some other issues. Interestingly enough car still made 387@wheels on 12.5psi. I got an email from MTR ,keeping my fingers crossed ... their mani at $1k is "dirty cheap" compared to alternatives...

Now here is my first major issue. As a lot of the guys on this forum running 1JZ with “The Drewgo" will find out pretty soon - his manifolds were not that great. They do not crack, BUT he copied the MTR Manifold Wrong OR someone screwed up in the process of making his flanges - the...

Got the diff on the bench. Wanted to make sure that it really is Cusco inside. Converted the diff to what I belive is the best for 1.5JZ - 4.1 JZA70/MA70 Hybrid 4.1. Adjusted the backlash and set the diff to 1 way. You have to know what is inside the stock diff ,to appriciate the Cusco...

There is only one answer here - there really is not any "off the shelf" adjustable upper control arms for MA70. The available options are: 1. Cut your stock arms and weld them (requires a very very trusty welder ,some calculations ,etc). I did this on my car and have some "-3 arms" in my...

I also have been running Dunlop Direzza Star Spec on my Supra ( 255/40ZR-17 all around) since their intro in 2008. IMO these are absolutely the best tires for the price when it comes to street grip tires! The only Cons of these ... I found the hard way - they should NEVER t be used or stored in...

Got the TKO differential out of the car ,it was too cold to do anything else. Plans are to check it ans see if I find Cusco Inside :evil2::evil2: ,adjust backLash set it to 1way etc.

You have to start by changing your front sway ,because it is probably the easiest. The bushings would be next thing on the list. These will both REDUCE your underSteer but they can't eliminate it.Eliminating the underSteer on street or semi-slick tires is a major challenge - from my experience...

I got the front suspension replaced (LCA ,UCA). It seems that I've lost training in melting the LCA toyoda bolts.At least I gained some confidence how strong are these bolts (DIN 8?) after I tried to cut them with my sawzall;) Intrestingly enought the steering rack had a major crack...

Your OverSteer has very little to do with your springs if you are already running 14k. It is more than likely caused by low static camber first and then sways , tires ,bushings ,etc. Post your current setup and geometry settings if you need any more info.

Pretty typical for countries with no drag strips - draging on old Military AirPorts. 2%+ incline requires some man power to keep the cars from rolling back too far from the start ;) I'm extremely surprised that the supra held up so well ,on concrete surfaces IRS+RWD never stands a chance to AWD...

There is a noticeable "spiral" at the beginning of the Dyno graph (see the Dyno video). IMHO MAFT Pro is a lost cause ,I found this after looking at my logs in 2006 when I first got it. I've spend some serious amount of time of almost R&D with TurboBob but never got this resolved. There is a...

As I said I got these from Dr Jonez (Adam)'s car together with the reamed spindles. I've asked him a few times to give me the original invoice for the arms so I could post the part numbers for the community ,unfortunately the only paperwork that I got was the original SPC instruction book which...
