    Yes, that holds the bump stop to the top of the rod. Ive had it all apart and checked 3 times and the Bilstein dampers definitely lower to car by about 15mm when using the original springs so with lowering springs, the drop must be about 35mm

    Big problems shock absorbers Bilstein B6

    Can you post up your actually ride heights to the underside of the outer edge of the arch for all corners. What profile tyre are you using also all corners

    Sorry if itís a repeat comment but are your sure the old springs are OEM supra parts

    Mate

    I forgot I was going to send you the numbers on my shocks which were supplied last year.

    fronts - 24-017930 followed by B46 1793

    This was an assembled front unit ready to fit. You can see the spring compressor fitted and the spring compressed so I could get the strut with OEM springs compressed to get the strut in place.

    I dont have a picture of the rears which shows the part number

    I got my sets from https://www.europerformance.co.uk/pa...sub_category=1


    Hope this helps

    Will do when i get chance tomorrow night. Tyres are 35 profile. Theres deffo a drop of about 15mm from just changing the shocks from standard KYB to the B6's. I cant even get the trolley jack under to jack it up now and i wouldnt really bother but now i cant get over the ramp out of the garage without a major scrape.

    Springs are 100% OEM standard springs.

    That shock in the pic is the rear mate.

    The part numbers are correct as ive checked with Bilstein. They sent me a diagram of the shock with measurements and all those are correct too. I can only assume that the Bilsteins do in fact lower the car a little and are designed to do so but adding lowering springs with them must give a fairly large drop as you get the lowering effect of the spring and the shock combined. This is all well and good but the reason i bought the Bilsteins was because i was under the impression they keep the standard ride height when using standard springs.

    Im also now in a catch 22 situation with the rears. I was going to buy the rears so they are all matching but the last thing i want to do is lower it at the rear too. I really could do with a 15mm sleeve that sits between the circlip and spring seat to lift it back to standard height.

    Just to also add, the strangest thing happened when i jacked the car up. The spring was now tight with the weight off. It seems the rod does not extend as far straight after there has been weight on the car but when left overnight the spring became slack again so im not too concerned with the spring being slack anymore, its the lowering effect thats now bothering me.

    Got mine here. Depending on the exchange rate, it worked out a bit cheaper this way. Delivery was only a couple of days. Paid €500 delivered for all 4

    So the update on this is that the Bilsteins will lower the car by 15mm if you were using the original Toyota KYB shock absorbers. They only keep the standard ride height if you are swapping from factory Toyota Bilstein shocks. Supras with Bilsteins from the factory must of been 15mm lower than Supras with the KYB shocks unless the springs that came with the factory Bilsteins were different/longer?

    Bilstein say making a 15mm collar to sit under the spring seat wont work (ive no idea why not as surely any rise in the spring seat will also lift the car) and the only option is for me to return the shocks and have them machine a new groove into the shock body 15mm higher up and then fit another circlip for the spring seat to sit on.

    This has now become a PITA! Im sick of taking them off and putting them back on and now ive got refit the old shocks to send the Bilsteins back and await them altering them then refit them all over again. I also have the exact same problem facing me when i buy the rear shocks.

    I looked into just selling the Bilsteins at a loss to get some money back and then buying some coilovers but HSD say their coilovers will lower the car by 20mm on the highest setting so im assuming no coilovers will give standard ride height but ive also emailed BC Racing to see if their kit is the same. The only other option is air suspension so i can lift the car as i drive into the garage but i really do not want to go down that route.

    Buy a coil over kit for the JZS147 Aristo or Soarer, same shocks just longer

    If you want a lift spacer machining up let me know. I can turn one up on my lathe. Its practically the same as moving the groove for the clip.
