Look at the spoon racecar, they are running a much larger front tire, with great results.

no, im not saying understeer, im talking about moment of inertia. this means whats is the resistance for the car to change direction. FWD cars have high moment of inertia for the front of the car. grippier tires in the front dont help any. its precisley why mid-rear engine cars like an elise or a cayman handle much better than front mid engine cars like the S2000, even though cars like the S2000 have 50/50 weight balance. TBQH the civic is my first performnace oriented FWD car, ive had only ownership and experience with RWD cars in the past. its been 2 months. but perhaps the front tires being wider are better suited to the professional driver? idk.

And as for the porsche comment, you still have me lost. It would be foolish to think that you would want a larger front tire on a RR car. While the rear would be more predictable, the car would corner significantly slower. Perhaps you're talking about a non-staggered setup, similar to what s2000 drivers do?

when you accelerate, there is a load transfer to part of the car where the engine is. in 911's, this means the back. the back is already rear heavy, but now its even more rear heavy. the front tires have little contact with the road.
lets say your coming to a curve the car can take flat out. you try to turn the steering but you dont see a proper response in the car. so you let off the gas. now the car slows down and theres a load transfer to the front wheels, the tires have mroe grip than and bam, instant oversteer. this is called 'snap oversteer'. pros know what to do, but novices crash. a way to reduce this is to increase the grip of the front tires. this reduces the 'snap'
there was another ameture tactic which was to let off the gas before the turn, and mash the pedal out of the turn. there was a cute little rhyme for it but it espaces me right now..
now, i think there is a misunderstanding here. im not talking about fine tuning here. tires arent the only thing that can effect traction. car makers tune the suspension as well. im only talking about ameture tweaks here. if the Si is set up a certain way, dont go changing it without proper investigation. the 911 thing was more of a little joke from back when people would keep crashing their 911s before TCS.
