So, the gtfour was called souless. I could never quite put my finger on why till recently. I think it earned that title due to Toyota making the road car more luxurious than a track machine. It was more refined compared to its raw econo based counter parts.
Due to its luxury status, it was numbed a bit. It is a bit heafty than it should be due to sound proffing and all the fancy extras. These we can remove.
I would like to dedicate this thread to determining what things Toyota did to soften up this car, so that we might come up with solutions for either fabricating or upgrading bit to give it more feed back, more control and better handling.
Things we know that soften the alltrac:
* The struts and springs.
The spring rates are too low and the struts do decent but are not quite up to part for circuit.
* Strut tops. Rubber tops are better replaced with adjustable pillow mounts.
* The rear diff cushion. Gives too mcuh slack in the rear end. Either a soild bushing or poly helps in this respect.
* Suspension bushings. Mostly due to being worn out in our cars. Superpro replacements help things out quite a bit.
These are the only things I can say for definate for now. I have replaced all of these with great results.
If you list an item, please explain why it is a problem. This should help lead to the solution.
Here are a few other items I suspect might be good for study.
The tie rod ends, steering rack, chasis mounting point and bushings.
