shock absorber size query

[Billy Mc]

hard to describe but here goes}

basically had a snapped spring on rear ended up changing full set for apex 35mm drop .
car is vec 1.9 cdti 16v sri springs are fitted correct way up
and correct load for axles.
problem is o/s/f is very stiff almost no bounce
i did notice on removing springs on front there were 2 different spring sizes.
i know the factory sri shocks are fine for these springs unsure about standard shocks
could it be that in the past it has had a standard spring and shock fitted on o/s/f and would this be my problem of the shock bottoming out due to not enough travel.
or anything else
cheers guys

basically im asking are sri shocks different to standard. eg shorter.
as i am puzzled as to why no bounce on o/s/f corner with new springs.
n/s/f and rear are fine
please see my op
thanks in advance
or could it be something ive overlooked

Yes, SRI shocks are different, and should be used if lowering from standard suspension (or use aftermarket sports short travel shocks as well).
