£250 option when new for the lsd.
80 had them fitted from the tickford factory, now quite a few of us have had them fitted.

i wont comment as im biased as ive owned mine for 5 years and wouldnt change it for the world. ive driven alot of faster cars and still would not change it, the fun i can have in my frp i have never managed to match in another car.
all i will add is that there is a big big difference to a 4.5-5k car than a 7-8k car.
ive seen some 4.5k cars recently as i have an involvement with the rpoc and some are becoming absolute dogs now, i know i could sell mine for 8k easy but then ive spent over 15k on it renewing every nut and bolt etc and respray etcand it never ends to keep them looking mint is a very hard task as they really do attract stonechips with the wide arches, hence why some look blue and white lol.
i think anyone that has driven one knows why they are special as it really is not all about speed, drive one hard down some twistys and id put money on it that you would stop at the end with a big smile on your face.
plus you never get bored of the pops and bangs on over run

..
get one you will love it and theres only around 350 out of the 500 left now so you wont see many about.
recent one of mine from duxford, where i managed to win best in show out of 49 of us there

.
one from my last trackday in it ( dont worry i moved to the isle of man for 2 years hence the plates to match my car frp241

.)
one i like from the ring
and you really never get bored with how well these stop you, ive never once had brake fade even after a full on track day
