Hi,
I've got a set of used uprated progressive springs for an Amazon saloon for sale. Might fit a p1800 too, don't know. I bought them from Amazon cars a few years ago. They have been on my car ever since, so have surface rust and not much, if any paint left. They are 20mm lower than standard springs.
They are great springs, significantly stiffer and more controlled than standard springs..they now
cost over 300 quid from Amazon cars and the equivalent are over
400 quid from Brookhouse. I have put shorter springs on my car now to lower it a bit more.
I want £130 delivered. Thanks.
