I hear waht youre saying. Personally I think no-one should push their car unless they have specifically set it up for performance driving. Safetys not a problem for me as my car has a very stable platform with 15mm spacers, Tein Suspension, Volk rims and 100kg shaved off the body. The Teos are very predictable in the wet and easy to control if they slide. For example, once i braked to avoid a bird at 120k, locked up the abs and steered around it with the abs on ful lock. The car didnt sway or roll at all. Did your celica come out with 16's? Because I think they are a far better tyre for that car - quiter, more comfortable and more grip as they wont skip on bumpy, wet corners like 17's will
