Just wondering, when compressing the front cones, how far should I compress them?

Until  you can  remove the trumpet. Remove the rebound stop to give you a bit more drop on the arm as well.

quick word of warnign, make sure that when you screw the thread into the cone before compressing, make sure it threds correctly and is into the cone as far as it will go. i started compressing and bang!

Very good advice indeed. The inner piece should go in about 7 turns. If the threads are dirty it can be a problem so a good squirt of wd40 down the hole left by the big bolt is worth doing.

i put a little bit of copper grease on the treaded section to help things as well. also a squirt of wd40 on the actual cone compressor tool (when you actually start compressing it) can help a lot!

Since we're adding tips...

 

Do the compressing with it sat on the ground so the weight of the car is helping you - wheel on or jack under the bottom arm (backed up with support under the subby, just in case).

 

You're also aware there were metric & unf versions of cones? Unless it's old  (solid mount subby) and original, it's most likely metric, but consider it if the tool doesn't want to screw in.

And mate.... Don't be putting ur head or anything near that tool or cone while ur compressing, the load you put it under is extreme! Just be careful, and doing the compression with the car on the ground is a wise move first!,

Also if ur using a cheap compression tool if minisport, watch you don't strip the thread!!!

P.s with the car d the ground and a cone compression on new cones it took two of us to compress it enough to get the hi low in (I stripped the thread on my tool)
