TT TYPE COILOVERS

The new TT type coilovers from HSD have been designed with every-day driving comfort as a priority. They use a twin-tube damper design (hence ‘TT’) which is less aggressive than the large-diameter mono-tube type dampers in the HR series. Spring rates are also generally 20-30% softer than the race-oriented HR series. In most cases the top mounting plate features a rubber bushing to reduce noise and harshness, but for strut replacements a camber-adjustable pillow-ball top is used for a larger range of camber adjustment.

Like the HR series the new TT uses an adjustable base bracket for easy height adjustment. The dampers also feature a 12-step adjuster for damping force. For a low-key appearance the aluminium lock rings and top plates are anodised grey, with black springs and brackets. The spring rates listed are our standard specifications. Alternative springs are available to order.
