D-Series Engines

• 350/250 - Best ride for a daily driver (DD). Great for commuting. Front may bottom out if set up too low.
• 350/350 - Good compromise, less understeer more fun. A modest concession to ride quality. This may be choppy for some drivers with short wheelbase models; Civic Hatch and CRX.
• 350/450 or 350/550 - Minimal understeer, quick turn-in, less roll, fast fun, good for drag launch. Rides rough on bumpy or poor roads.

B-Series and K-Series Engines

• 450/450 - Good compromise, less understeer, less roll more grip.
• 550/550 - Minimal understeer, awesome handling, quick steering response, good for drag launch. Rides rough on bumpy or poor roads.
• 550/650 - Good for track cars equipped with a front end spoiler or splitter and street cars running super-wide wheels tires and low ride heights with a very stiff ride.
