And I assume they're being used with your stock shocks?
If so, expect the shocks to fail in the near future.

In general, these eBay coilover sleeves are absolute shit.

When your stock shocks fail., take a good look at a set Koni Yellows and Ground Control coilover sleeves. If your "R1" sleeves have locked up yet, they will soon.. all the cheapo no-name sleeves will.

If your budget is tight, skip the cheapo coilover sleeves altogether. KYB AGX shocks and Tein S-Tech springs will also produce a reasonable drop and still give you the needed wheel travel to ride with reasonable comfort and safety.
