$1100 on Costco's website for SLX + $200 for extensions = $1300 vs $1420 retail for the EXT. ($1395 at Summit Racing)
Would the SLX + extensions be more flexible? I wonder if the EXT would be too long for many smaller cars? If that's the case I'd go SLX + extensions. If not $100 more to not have extra parts required is maybe worth it... but then again the extensions would probably give it a couple more inches of lift by the looks of it.
After spending way too much time figuring out how to jack the car up without damaging it using a rubber pinch weld block + a hockey puck, cutting slots in my jackstands for the pinch weld to sit into, ugh... one of these lifts + the alum pinch weld blocks seem like a good idea. This will make it so much nicer to work under the car too...
I know what I'm asking for for Christmas this year!
