fallen99angel Posted June 9, 2004 Report Share Posted June 9, 2004 heres another question, Im sure its a dummy, I have an offer on 20" chrome wheels for my sts and i was wondering if the brakes will be strong enough to stop 20" wheels, or if i have to upgrade them, Im sure the best will be an upgrade, but that will be another 1500 - 2000$ as well. Someone with experience with 20" wheels on their sts with the oem brakes??? regards henrik Sweden Link to comment Share on other sites More sharing options...
jcheadlee Posted June 9, 2004 Report Share Posted June 9, 2004 I roll 20's on my sts, I would think it would be best to upgrade the brakes, but mine have been just fine so far. seem to stop just as fast, doest not seem to be wearing anything out any faster etc. etc. I really only drive mine on weekends though, not a daily driver Link to comment Share on other sites More sharing options...
fallen99angel Posted June 9, 2004 Author Report Share Posted June 9, 2004 basicly i only drive the car by summer, no everyday, but quite often, but I was offered a deal on wheels spinners and dustcover and tires for about 1400$ the wheels have a few months to the name, but have no dents scratches and stuff, I just dont wanna bust the brakes on the car, since I also have an offer for vault chrome wheels for 900$ regards henrik Sweden Link to comment Share on other sites More sharing options...
danbuc Posted June 9, 2004 Report Share Posted June 9, 2004 Coming to a dead stop quickly with 20 inch wheel is possible in an STS but not recommended with stock brakes. The car come with only single piston calipers in the front and the additional rotating mass of the larger rims will make it harder to stop as fast. Not to mention that you will be more likely to prematurely wear out the brake pads due to the increased force required to stop the car. If you are looking to upgrade, Baer Brakes makes a nice conversion kit for Cadillacs. There is a link somewhere on the caddy info home site.

JLAWS Posted June 10, 2004 Report Share Posted June 10, 2004 I have a 98 STS with 20" Wheels. Stock brakes are fine for city driving and "responsible driving". But if you are racing someone and doing over a 100mph and need to do an emergency slowdown/stop, your brakes WILL fade. It happen to me and I had to use 2 feet on the brake pedal to slow down.!!!! An inexpensive upgrade would be just to go with cross drilled and slotted rotors from Tirerack. I have those for the front. I had rears custom cross drilled but those just seem to be for looks. The front ones are the most important. They made a huge difference and don't seem to fade at all. When facing the same scenario, rather than fading you'll just end up hearing a whirring sound as though the rotors are cutting into the pads.

rek Posted June 10, 2004 Report Share Posted June 10, 2004 If 225-60-16 = 26.6" Dia. and 185-45-20 = 26.6" Dia., I don't know if the pads/calipers would "know" what size the wheels are. If the "dubs" are larger than 26.6", they wouldn't have the same mechanical "leverage"... rek Link to comment Share on other sites More sharing options...
JasonA Posted June 10, 2004 Report Share Posted June 10, 2004 It's the weight. A metal wheel is heavier than a rubber sidewall. The rotational mass does cause more leverage on the engine/brakes, and will make it harder to both accelerate and stop.
