Not sure about the BLOX with DC2R shocks (gut feel is probably not as its mounted to the lca diferently and doubt they can take both types)

Next best is KYB AGX shocks (to suit EG LCA) combined with DC2R springs. I have this setup and works well. Its not very low, but can be driven daily without a worry, with good firm track suitable springs. The adjustment in the shocks firms up nicely for track work, pull them back for kidney friendly ride (but still firm).

Combined with a rear bar (I run a 20mm whiteline adjustable on firmest setting) and you have good balance too.

Recommended and tested by me

If you have a bit more budget Koni Yellows shocks would be better again, for more finite and range of adjustability.
