March - April Updates

Welcome to UCSB Racing's website. We compete June 4th-7th in Illinois and we are working overtime to get this finished for testing and tuning. This is a big update, so kick it into high gear and hold on.

Does this spark your interest? Kyle is testing out his freshly welded swing-arms while Zach is welding on suspension mounting tabs.
The chassis at 57 pounds with engine mount and no mounting tabs.
A few additional members were added to support lateral suspension forces. The suspension mounting tabs are tacked in as well.
Dean, Matt, and Tucker establishing the correct locations for seat belt mounts.
Ahdi's laser cut steering rack mount. It fit beautifully.
Steering column is supported by sealed bearings.
Lower steering column and a peek at the brake system
Transaxle shifter cable and mounting
Custom shifter with authentic Paul Silva hand painted lettering
Dean removing some material from the transaxle so it will fit in the frame
Our brake is sourced from a Jeep wrangler and came in a plastic housing which wasn't necessary for our purposes.
We weighed the housing and made some steel mounts that were much lighter and slimmer
Zach getting creative with his welding positions
Terry and Ahdi battling with the firewall
The first piece of the body paneling and belly pan
Take a minute to watch the time lapse video of the fiberglass work.

Tim is the head composite specialist. Here he is cutting the panels into separate pieces.
Callie Barker is our head seamstress and is making the safety harness holes larger in our seat cover
Here is the cover with a larger hole
OH... and here is Ahdi testing out the cover at spring insight
Tucker modeling for the nice people
Wheel adapters to convert from the Gravely Trekker hub bolt pattern to a standard Polaris size

Our goal when designing the rear suspension was to idealize camber and toe. This is very easy with A-arm/H-arm suspension systems but proved to be extremely challenging for a 3-Link semi-trailing arm suspension. We tuned the radius arm lengths and mounting positions for 20-30 hours using Solidworks. The ideal geometry must take camber, toe, track width change, and drive shaft plunge into account.

Brake rotor mounting. The Gravely Trekker hub was drilled and tapped using a rotary table and the inside of the factory Polaris rotors had to be lathed outward a bit.
Upper control arm caster adjustment spacers
Gas pedal is mounted. The throttle cable and return spring rest between the two chassis tubes out of harms way.
Throttle cable mount
We need raised racing numbers and the carbon fiber should give us at least 5 more horsepower
It gets really hard to keep track of things on a team of 10
Dean is on the job
