Haynes Roadster or Locost Seven?

[david_hornet27]

I am a little confused as to what my car is! lol

It is a Seven style car with Cortina uprights and brakes at the front with a Sierra steering rack. At the back I have a Sierra diff, driveshafts (independent suspension) and brake drums. The donor car was obviously a Sierra as the speedo, steering column controls and handbrake are from that car. When I bought the car it also had the donor engine (1.8 Pinto) which I have now swapped out and replaced with a 2.0 Pinto.

It is listed as a Locost Seven on the log book. I thought the Locosts were built using Escort live rear axle and donor parts with Cortina parts at the front. It also seems a bit wider than other Locost Sevens I have seen, I guess because of the Sierra running gear at the back.

So what do I have? A Locost Seven or a Haynes Roadster. Or even a Haynes Seven or a Locost Roadster??


Thanks...

Thanks, I guess that's what I kind of thought so it's nice for someone to confirm...

A quick way to check if its a Roadster is the shape of the front frame of the chassis ...if the upper corners stick out then its probably a Ron Champion based chassis , maybe a Mcsorley chassis which is wider than a "Book " chassis ( this being the Ron Champion chassis) & altered to accept the Independant rear suspension of the Sierra running gear.

The Front Frame of a Roadster is quite different to the Ron Champion version.

Probably a locost hybrid, there are plenty about. Suppose its very similar to adapting the haynes to accomodate mx5 running gear

He did and like others have said there are a lot of hybrids out there.
The downside with altering things to a given design ie: making it wider is nobody makes panels that fit so in the even of a shunt you are into repairing rather than buying new stuff.

The only people who did body panels for the Mcsorley plans were GTS Tuning, there are made by the scarlet pimpernel though

Mines a hybrid - a locost +4" chassis with Haynes roadster front suspension and a BMW E34 rear axle assembly (carrier beam, semi trailing arms, anti roll bar and hubs).

I'm calling it a Roa-locost-der

Do not touch that.....it will come and haunt you.
I have a McSorley 442 with Rorty IRS designed rear end for Sierra. Even allowing for the wider body of the 442 the Sierra diff and shafts would not fit. Eventually had to move the the carriers out by another 80 - 100mm on average to fit.
Deja vu for the rear shocks - with the Rorty uprights and built to the letter of his plans, I was left with only 200mm for shock and spring when the car was set on riding height Mayor surgery again so save the day.

Sad part, he did not even responded to my mail informing him the plans are in error.
