Back on the Road, Well Almost!

With the Southwest Regional Heat approaching fast (23rd June, be there!) the car is almost back together after the major overhaul that's been going on since we got back from Silverstone. The most striking new feature is the new slimline look,

This has been done to save both weight and rolling resistance and with a track of over 600mm should have a minimal practical effect on stability. Other weight/resistance savings have been made in the drive train. We have switched from two cantilevered axles to a single transaxle at the rear which has let us get rid of two bearings and their supports. We have also simplified our drive train by removing the CVT gearbox, replacing it with just a regular cassette hub to act as a lay shaft. This has saved us loads of weight and resistance but we do lose out on flexibility on the the track with only a single gear.

The brakes are now mounted on the front wheels. The regulations demand two wheels be independently braked so we have had to mount them up front. This means we take a bit of an aerodynamic hit but this is more than made up for by the weight savings at the back.

The car has also had an aesthetic spruce up with a new coat of paint and brand new decals, just to finish her off properly. There are still a few more tweaks and nudges left to do this afternoon but she should be ready for a pre-race shake down at the end of the day.

More Modifications

With the experience of the Season Opener under our belts and now knowing how we will be affected by the battery change, the team have been making some modifications to the car to improve the performance ahead of our local qualifying race in June.

One of the major changes, due to the overall reduction in speed is that aerodynamics has become slightly less important but weight has become more important. With this in mind we have put the car on a crash diet. We have removed as much material as possable from the rear sub frame without compromising its strength. This includes the replacement of the cantilevered drive shafts with a single through axle.

This allows us to remove two bearing blocks and theirssupports from the frame but it does mean moving the braking system to the front wheels. One of our kind sponsors, Teagle, have offered to make our new steering assemblies which will now include the necessary mounting points for the brake calipers and also give us much more control over the precise geometry of the steering system.

While the car has been stripped down the team have also been working on the surface finish. We are trying to get a perfectly smooth finish to reduce turbulence as the air flows over the surface. With only a few weeks left until our next race we will have to get cracking to get all these mods completed but we will be working every lunchtime until the car is back on its wheels once more.

Reassembly

Today the boys continued the reassembly of the car, getting the subframe bolted in, the steering linkages and the rear drive shafts installed. Quite a lot of progress for one day, although it was a bit disappointing when one of the rear shafts had to be removed again after it turned out that the brake disk was on backwards. You would have thought we would have learnt, the same thing happened when it was assembled the first time! Work has also continued with the wheel cowlings, they are looking AMAZING in red, as in the pictures below:

Looks Like Progress

Well today's progress was monumental, the rear of the car was drilled and the subframe and shafts were mounted into the main chassis. It is definitely looking like a car now, well the back end is anyway.
