Wees and Vees work best with the front lowered more than the rear due to aerodynamics, mainly due to the unpainted black plastic ramp under the headlights. Unfortunately, the rear can be safely lowered more than the front. The limits are about 28mm on the rear and about 21mm on the front before parts start crashing together. ABS Wees with fork braces can start hitting the brace on the ABS plumbing closer to 10mm. You would do best by lowering the front to those limits. Still, avoid very high speeds. The faster you go, the more the front wheel will effectively lighten up.
