Well done Steve on a great build and a great read.

I assume that the cables I see are droop limiters, why the multiple holes in the lower bracket or is it again for lightness?

What are you doing for a handbrake?

Really interesting photos, great work, its many magnitudes harder to work within existing parameters like the chassis, suspension etc like you are than just building a silhouette racer.

Yes, lightness. Me? Anal? Perish the thought



Working with the orignal chassis has been a challenge, but a fun challenge.

Guru (Devanagari ????) is a Sanskrit term for "teacher" or "master", particularly in Indian religions.

Looks like a hydraulic handbrake? If so, do you have an auxiliary mechanical handbrake rigged up for MOT's......... It's all looking very good BTW thanks for sharing the photos and the updates.

Yes, I know that but whom are you referring to? Certainly not me.

Certainly is. Mechanical handbrake not required, as noted in the MOT manual:

"Hydraulic parking brakes as a sole means of operation are not acceptable on vehicles first used on or after 1 January 1968. However, they may be used to assist the application or release of a mechanical brake. "

My car is a 1967 model.

I have been studying the rules to see what can an can't be left off. For example, I only need 1 rear view mirror.

Adding lightness

As long as members are interested in progress I am happy to post.

[stevebroad]

OK, looking for advice/suggestions.

Haven't looked into fire suppression yet, but will need a system. As always weight is a consideration, but not at the expense of car or me

Any ideas? Also is there a preferred location for cylinder or can I position it anywhere?

Electric or manual?

Looking to protect engine bay, cockpit and boot.

Wow nice build

Having owned a Dax Rush with 400hp going to the Rear wheels your going to need some sticky tires to put that power down, i used to be able to smoke the tyres at 100mph in 4th gear
