I spend much of my weekends repairing 'improvements' to members Supra's and the no. 1. wind-up, is jacking the damn things up, which invariably takes more time and effort than the job in hand.
It goes something like this; first use the OE jack to lift the car up a bit to get a little trolley jack under cross-member, then pump it up to max height, using a socket extension for the first half of lift because there's no room to swing the jack handle, then install axle-stands, then repeat at rear of car.
This gives just enough room to wriggle under like a maggot and look at the problem. To then get under with room to work, entails using wooden blocks balanced on the trolley jack to lift it front and rear up to max height on axle stands. After the job is jobbed, then lower it back down with the above sequence in reverse order to find that the 10 minute job had wasted most of the day for 2 blokes.
At the weekend I discovered that my trolley jack had been stolen, it was low enough to get under mine yet lacking in lift so have replaced it with an upgrade. It's a 45kg beast with a 3 tonne rating, I wasn't after such a monster but it cost less than it's lesser brethren and has a lower (70mm) entry and greater (508mm) lift, which will get under anything I need it to and raise it up to max axle-stand height in one lift.
It's one of the best presents I have ever bought myself and rate it as a Supra owner's must have.
