i’m pretty sure sasha has custom wheel wells to fit bigger rims/tires
i run 9" wide in front and i rub the wheel wells on stock s14, you will rub even worse on s13 chassis (i think)
12" wide is just ridiculous and is just plain dumb on a street car.
i don’t even think sasha runs 11" in front
when you run wide wheels, it accompanies having wide tires.
wide tires with wide rims = the more traction, obviously.
the more traction in front requires more effort for the steering rack to work to turn those massive rims/tires
also, when turning theres forces exerted on the steering rack, tie rods, ps system and etc that will overwork these parts, rendering them less effective. these parts will also break down a lot faster. (i remember reading on zt that sasha broke his steering rack this season, or it was something else that had to do with steering)
if you’ve ever tried running a wide tire, then going and running a smaller tire in front, your steering feels a lot more responsive and in some cases, lighter. lots of of ppl run smaller rims in front like 15" just for the more response you get because of the less effort to turn the wheel, making it crisper and more precise.
just like how you see in most mortorsport prepped cars, lots of them run staggered probably because of some of the facts mentioned above (obviously a lot more complicated but something along those lines).
and…that is my reasoning. i’m not talkn out of my ass, i have tried running both wide and skinny in front. that is my experience and observation
ps: if im wrong in any info or if i’m missing anything, feel free to comment. its always nice to learn more or be corrected if wrong.
now commenting on this, there IS such a thing as overkill when it comes to wide wheels and tires. According to skip barber (professional racing school) a larger/wider tire does not necessarily mean more grip. in his book he talks about tire contact patch, quoted below:
An automobile contacts the road surface through its tires. A tire’s contact patch is about the size of a postcard. The contact patch area for any given weight automobile at rest remains constant regardless of the size of the tire.
Sometimes you hear people say that they put wider tires on their car to get more rubber on the road. Wider tires
will change the shape of the tire patch, making it wider,but the total area of the contact patch remains the same.
This is due to the relationship of weight per square inch that the tire is supporting; if the patch gets wider, it will
also get shorter.
you can read more about this, as this is just the tip of the iceberg
John, you just got served bro.
