I hear ya on working on your car yourself. The dealership costs too much and performance shops have done damage in multiple areas to my car. I don't trust anyone else.
just make sure the jack and jacks stands lift the car to an acceptable height for you to work under it. I've gotten jacks that were only good for getting your wheels off but not for comfortably working under your car. Although you don't need the weight capacity, the SUV 3 ton and 4 ton jack stands have a much higher lift height. If you don't need to remove your wheels (which you can do with the oem mini jack), you might want to get ramps which lift high obviously since they lift from the wheels not the frame (sturdy Rhino ramps for $20-$30). I have ramps and jack stands which would be good for a clutch job. Or if you're getting your rotors resurfaced, get 4 jack stands.
The ramps are good for motor oil/gear oil changes and getting Cold Air Intake
filters off for cleaning, or for doing the ghetto unbolting your stock muffler for racing at the track...
For other people: If you live in an earthquake area like in Cali, some people feel more comfortable with ramps than jack stands. You just never know...when you could be unlucky. And get the nice creepers that roll well, not the cheap kind so that you can roll out fast in case an earthquake starts, or one of your enemies comes by to knock you off hehe
. It's no fun anyways to use a creeper that doesn't roll.
I'd say get a jack that lifts at least to 18.5" and jack stands that at least match that height.
there are those small wimpy $29.99 jack/jack stand combos that can't lift your car from the center bar attached to the subframe. don't get those.
another issue on the jack is you may want to get an expensive low profile racing jack if you've lowered your car significantly or plan to. The racing jacks normally cost between $100-$150. I got mine on sale for like $70 from Pep Boys with the rebate. With Eibach Sportlines I couldn't easily get the normal service jacks under my car w/o first using the stock scissorjack which takes too long to turn that handle (and then what's the point?).
