Lightened Yaris

[HTM Yaris]

Tom: for track and autox I take out the rear "junk" so that I can utilize oversteer . In the mountains I leave everything in so that I can utilize understeer . I don't want my tail to be in the opposing lane !

Jason: First of all , I really admire what you have done with the Yaris

But it is really unfair to compare your fully track prepped Yaris with a street driven Yaris . I mean your Yaris looks like it has the correct weight reduction measures ( in all 3 planes ) . I mean really , those Goodyear ( which have extra stiff sidewalls BTW )slicks are enough to keep any vehicle from tipping over Not to mention I feel you have a custom suspension among other things . Try this , put your stock Goodyears on and put your glass back in or up ( not sure if you removed/replaced your glass ) . I feel certain that the stock tires will roll onto the sidewall then the wheels will dig in to the tarmac , then loopedy loop , you will make some body shop happy

Light is might . That is correct to a point . To the point that safety is compromised .
The OP doesn't have a roll cage to stiffen the Yaris up after the reduction in weight . Nor does he have 10.5" slicks with a custom suspension . Nor does he have the driving experience(Yaris) in a panic/performance situation like Jason does .

In no way am I saying that weight reduction shouldn't be done . I'm just trying to point out the potential pitfalls . Another pitfall I forgot to mention is that the Yaris will be more likely to hydroplane with weight reduction . I can't speak for anybody else , but I would not want to be hydroplaning on the downside of a 12% grade Not saying that will happen , but the potential will be increased with weight reduction .
