Four Lane SR2 - Spool Heads Racing SR2 1:64 Scale Diecast Racing Track - Quad Lane Straight Track - Hot Wheels

UPDATE: Connect track pieces using two of the single SR2 connector instead of trying to use the dual connector. It works so much better!

Here is an update to the Spool Heads Racing SR1 track. The SR2 has better walls that work an higher speeds. SR2 dual lane is also compatible with SR1 single lane and four lane track, giving a lot of great options for track builders.

Also search for single lane SR2 and dual lane SR2.
