Posted a new video on my signature below, copied again in this post for you to see as well.

The video is of Michael Levitas driving his standard Nismo R35 fitted with a DSC Sport controller lapping Virginia International Raceway.

His time was 2 minutes 1 second and sets a new lap record for a production car at Virginia International Raceway.

Putting this into perspective, that's a good second faster than a modified Porsche turbo on race tyres is capable of.

Pretty special result for the GTR and the DSC Sport controller.

That is quite good, but how does it compare to a lap in the standard car without the DSC fitted?

Sadly without a proper comparison to a lap of the same car and driver but without the DSC unit it's really rather meaningless.

Hugh, I think the only way you'll make serious inroads here is to have a driver of professional standing, or a known 'high calibre' driver take a couple of cars out with and without the DSC box.
If you could organise:
- stock CBA car
- stock DBA car
- stock EBA car
- Litchfield suspension car

And provide evidence of improvements from stock along with some empirical feedback from the driver, that'd go a long way to satisfying the people's wonderings on the kit.
Bringing a unit or two to a trackday with a laptop would also be a positive step. Otherwise, with no direct comparison, people are left somewhat cold.

Thanks guy's,

Understand that you would like proof of performance and this will come as more users are tempted to try the system.

For me the transformation in everyday comfort more than justifies the investment.

If you have a good track history and would like to work with me to prove the before and after performance of the DSC Sport controller, get in touch and I will do my best to work something out with you.

The only track car that I have so far set the DSC Sport suspension settings on is used at Sepang. The customer has an 800 BHP car with Litchfield suspension + Litchfield castor kit and was able to lap 4 seconds a lap quicker first time out with the DSC Sport controller fitted. The customer won his class with ease.

There will be more to come from this car, but I have not been able to work with the owner to develop the settings further.

Referring to Steven's comments above you will note that his suspension needed fine tuned to go from slight understeer to point and squirt, this is in a 1200BHP car that is seriously quick. Most of us drive our cars on the road day to day and much as lap times are an easy way to judge performance, it is the daily driven manners as described by Steven that will be of greatest value to the enthusiast driver which I venture is most of us.

There are other soon to be customers that have significant track experience with the standard suspension controller, that will be able to report back on how the handling has changed and what the lap time improvement is.

I will also be working with some cars fairly soon to set-up the launch settings and will be able to report back on the performance with the standard controller versus DSC Sport.

I'm so sorry to labour the point Hugh but this is a question of providing empirical data rather than anecdotal evidence.

It's about objective facts not subjective opinion.

Failing that being able to drive a car with this unit attached and the ability to turn the unit on and off to experience the improvement "on the fly" would go a long way to bringing you sales.

I think there are two parts to this
1. What impact does the controller have on the road for driver and this can only be judged by the driver and how they feel the car handles. Having been in Hughs car on the backroads to knockhill i noticed a big improvement on the handling on a bumpy twisty B class road. This is subjective but all comments so far back this up although the number of drivers using it may not be large.
2. On track - Unless you have control conditions and drivers and an empty track as per the points above by Johnny G its difficult to provide scientific data if its faster. At the end of the day any one who purchases it unless you can drive the car faster around the track with any benefits it provides the scientific data doesn't matter to you. Knowing your best lap times at a track then fitting it and checking times and concerning speed seems the best way to prove to an individual if it has benefits

Andy, Johnny and Graham,

I completely agree with your points that a before and after fitting the DSC Sport controller would be a great way to provide the track performance comparison.

I am currently speaking to some owners that have lots of laps under their belt with VBox results to refer to that will be able to provide feedback in the near future on their results once they have a DSC Sport controller fitted, you will hear about it on this thread as soon as results are available.

As described above, at this time, I only have experience with the one car which delivered a 4 second a lap improvement on a 1 minute 30 second lap time, the owner was understandably delighted with the result.

The DSC Sport controller is well proven on track with Porsche which are also fitted with Bilstein Damptronic shockabsorbers.

The points that motors makes above about the road manners that the DSC Sport system brings are really important, since this is where most of us will enjoy the greatest benefits of the transformation.

- The round town driving over speed bumps and poor surfaces.

- The open road where the improvements to braking stability and cornering are really significant.

- The drag launch settings on cars that have a proven history will also be available in the near future.

Most of the above cannot be measured with a stopwatch, nor does it need a professional racing driver, it is an easy and instant assessment that all of the those that have experienced the system have commented on.

I appreciate your patience while I gather the data.

Thanks

Hugh

Thanks for the replies Hugh.

Would you consider having a unit as a trial item so that it can be used before full purchase?

I'd be happy to pay a deposit of the full amount then if I decide against taking one, take off shipping charges?

I'm going over to Spa next month for 2 days, Jake is also attending. I could possibly ask him to drive my car for a few laps with and without the unit installed? I have a vbox sport unit too and can capture the info.

How difficult is it to uninstall/reinstall?

Thanks charles charlie,

As discussed by pm, I am happy to give you a sale or return trial.

For me this is a no brainer, it is soooo good, there is no way you would want to part with it after fitting.

Tin,

Spa sounds like a great place to test the system, VBox will add certainty to the results.

The unit takes me about 20 minutes to fit where the glovebox is fully reinstated.

If you were to leave the glovebox out you could swap the units in about 5 minutes.

Part of the service I offer is to tune the suspension maps for your car, not just for road, but also for any tracks that you might attend.

It is important to note that we would need to spend some time adjusting the settings to suit your tyres, anti roll bars and driving style, so would need to fit the controller as soon as you are ready to allow time to set everything up.

The map adjustments are necessary to accommodate different tyres, anti roll bars, suspension and driver preferences.

On track, a car that slightly understeers can be really fast if the driver is brave enough to use the throttle to move the rear end out, it's not so easy to drive a car set-up this way though, which is where the conversations about driver preferences vs racing driver setup kicks in.

This is all about creating settings that provide confidence for the driver to suit his / her driving style

Thanks

Hugh

Thanks Hugh, will be intouch

Am interested to see how it softens the suspension up for road driving

I don't track my car so can't comment on lap times. But since getting the DSC I'm using my car as a daily driver. I go over around 25-30 speed humps in my 6 mile commute and it was too much to bear even on Litchfields suspension. But the DSC softens it right up in fact i had to get Hugh to stiffen things up in comfort setting.

The only thing it lacks is the speed setting from 0 rather than 50. But that's minor.
