axel weight of 1.4l with a 1.6l engine swap

[Spiegel]

Could anyone please help me out? I've got a 1997 3 door mk4 it was a 1.4 but now a 1.6. I have found a set of coilovers reduced from £600 to £450 but they say they are for cars with a front axel load weight of less than 800 kilo's as i have not stats for the 1.6 engine i was wondering if anyone could help me out?
