is it a safe thing to do?
if you can't hack your tranny, the concept of "dubs" wheels cramming the wheel wells full is a decent option, or just bigger wheels and tire. Taller rubbers on little wheels actually hurt more than gain. It is a tall tire tale (haha). Most well disciplined trannies have non-straight gear and change quite dynamically to this one simple move.
I can use my own example of a old subaru, 15 inch wheels were difficult to find, but ,anyway, it came with tiny 13 inch wheel tires (23.2 inch diam). The same rpm, given the japanese wonder tranny, does 80 instead of 65 with 25inch diam..engine runs out of power first. This also increases safety, a thought for you tall gear swappers and low tire ratings. Seems the saturn went to a higher ratio for a reason.Alot of times, more than not, higher ratios OEM mean a weakness someplace, even though engine has enough power to go much taller geared. I learned the hard way...
Are the wheels the same as the saturn with tall gears as the one getting the swap?
