I only used it as a quicky to check the meat on my Brake pads!
And it let me down. Big time.
ive got a halfords trolley jack and it fits under my cup packed 182 comfortably. Might be a bit of a squeeze if your lowered 20mm.
Could always buy one and try, just return it if it doesnt fit under your sills.
Axel foley is my friend as well
Yeah I have no intention of ever getting under the car, it's just to jack the car up and take the wheels off!
I am about 20-25mm lower than standard
Renault jack ins't crap by any means user usualy are the problem.You can get one from Machine Mart/ Halfords for about £20 that are 2 tonne and will do a sufficient job, if you only want a cheap one. I've NEVER used the Reno jack, as it's beyond crap!
