HSD Smoothie Monotube Coilovers.

The background
HSD HR have quickly become known as one of the best quality coilover conversions available in the sub £1300 category. They are compliant, and extremely well damped. Using vastly superior monotube damper technology, they offer a much more comfortable ride for the given spring rate than other coilover brands, making them suitable for fast road use, as well as serious track work.

The Smoothie
The HSD Smoothies have been made to accommodate those customers who want an even more road focused coilover solution, Where you want the ride height adjustment, and the majority of the handling benefits, but with more of a focus on a comfortable ride.

About the HSD HR (that the smoothie is based on)

The HSD HR coilover is exactly what the performance tuning scene has been cry out for. No longer do you have to accept an inferior/compromised product when spending less than £1000 on coilover suspension.
The HSD HR has been specced by HSD Europe, for our roads, and tracks, with the knowledge and experience gained by HSD Europe using the now world famous Driftworks Control System Coilover made by HSD.

Many people are familiar with the Driftworks CS1 coilover, and it's achievements in competition across the world. The HSD HR now distributed by HSD Europe is actually built to exactly the same specification as the Driftworks CS1, just distributed under the HSD factorys own brand, as HSD Europe are now also able to offer the same high quality coilover solution for front wheel drive, and four wheel drive applications.

FAQ

Why are only some models camber adjustable?
With strut type suspension like on the front of an S13, S14, S15 Silvia or AE86 Corolla, the damper is an integral part of the suspension structure. This means that changes in the damper position can change the camber and castor angles of the front suspension. Where this is applicable, our front coilovers include camber adjustment. In all applications where camber can only be controlled by adjustable suspension arms, non adjustable pillowball top mounts are used.

What are the spring rates?
Smoothie spring rates for S13, S14, S15 and R32 GTS Skyline are 6kgf/mm front and 4kgf/mm rear. You will find that they give a more performance orientated ride, without the terribly bouncy damping associated with cheap low quality coilover kit's using equivalent spring rates. We have tested them for track and road use, and find these spring rates to be ideal.
Other models have a similar reduction of around 2kg in spring rates over the normal HSD HR spring rates

Are these available for any other cars?
What we have listed is the applications that are currently stocked in the UK. However we are constantly designing applications for different models, so keep watching this space, or drop us an application request with the contact form.

How low will I be able to get my car with these coilovers?
There’s a wide range of height adjustment that will allow you to set your ride height anywhere between a subtle, sporty lowered stance to completely slammed on the floor.

I don’t know…. what if I’m not happy with them?
We’re so sure you’ll be impressed, that we’re offering a no quibble, 30 day money back guarantee with our coilovers. Contact us for more details on this.

What are Monotube dampers?
Most uprated or aftermarket dampers are twin-tube design with low pressure gas to try and keep the oil from foaming as the damper moves. The Monotube damper design uses much higher gas pressure to better stabilise the oil, even under extreme and prolonged use. Because of the larger capacity damper (approx 30% increase over stock) heat dissipation is also greatly improved.

Why are some applications inverted?
With strut type suspension like on the front of an S13, S14, S15 Silvia or AE86 Corolla, the damper is an integral part of the suspension structure and as such, sees very high lateral loads in multiple directions. With the conventional upright design, piston rods can bend and even snap under extreme loads. The inverted or upside-down Monotube design as used on our strut models has massively more lateral strength when compared to an upright setup, so is a lot more robust and geared up to cope with whatever you can throw at it. With most rear suspension and with double-wishbone type front suspension, (as on the Skyline) very little lateral forces are seen, so the conventional setup works fine there.
