Chassis mods for GTE SE5 in HSCC 70s Roadsports

Post by Folliedouce » Thu Jan 23, 2020 4:12 pm

I'm planning to race a GTE SE5 in the HSCC's 70s Roadsports series. The regulations are quite restrictive as to how much the chassis can be modified, and I'd love some advice, please. I've listed the relevant regulations, with my queries in italic/bold type:

The front and rear suspension must be as original, however may be strengthened for safety reasons. Is strengthening necessary? - have read somewhere that (front) not a strong (ha-ha) point on Scimitar

Shock absorbers and springs may be changed. Single tube, steel adjustable shock absorbers are permitted as long as they are the same size and located in the same position as the original components and do not have remote reservoirs. Suggestions, please?

Suspension mounting points must remain as original.

Anti-roll bars sizes are free, may be adjustable and may be fitted to the front and rear suspension if not fitted in original manufacture. Have seen pictures of Scimitars listing like something in Royal Navy. Standard front roll-bar looks pretty beefy, but more needed? Rear axle looks well located but no anti-roll bar (?). Can/should one be fitted?

Anti-tramp bars, or a Panhard rod, or Watts linkage may be fitted to cars without additional rear axle location. As above, looks well located as is ??

Original bush material may be changed. No rose joints are permitted on any suspension components unless used in original manufacture, except rose joints may be used on anti-roll bars providing that the geometry of the suspension is not affected.

Adjustable spring platforms are permitted. Wot's a 'spring platform' ??!

Camber alterations are permitted. Does a bit of negative (?) camber help? Presumably adjusted by shims (?)

Sorry this is so long, but any help much appreciated.

I'm no expert, but I think "adjustable spring platforms" refers to the lower collet on a spring/damper combination, which can be threaded, allowing height adjustment.

Shockers for Scimitars come in many styles and variations for damping, rebound height adjustment etc etc, just look around for what you want to achieve

The Scimitar uses Coilover shockers, these are available with a threaded bottom mounting for the spring, so therefore the spring platform can be adjusted.

The Scimitar front suspension IS ALTERED by shims from the factory.
I would have thought it might be a handy way of getting the tyres to grip just as in F1.

The Scimitar rear axle already has Watts link and trailing arms

Just my Tuppenceworth, for what it`s worth.
The racer boys will be along to advise correctly.

Can I assume from your questions you are NOT a LONG time Scimitar driver :roll:

Now you mention it, of course I know what a 'spring platform' is !! - never knew that's what it's called. Doh.

Love gtse8's comment assuming I'm "not a long time Scimitar driver". When my wife and I married in 1971 (48 years ago!) our first car was..............a GTE SE5 !! Trouble is that it's such a long time ago I hardly remember anything about it, other than it was considered quite a jammy car to have at the time ! But am I "a long time Scimitar driver" in these circumstances, especially given my (lack of) memory of it ??

Sorry, but anyone who has owned/driven/raced LOL a Scimitar recently would have not needed to ask your questions, they would already be aware of these tekernikle traits. :W :lol:

Give us your name and location please, it will help US to help you :wink:

Few points

Welcome! :D
Ref car mods, competition is more specific and specialist than building a car for the road, so those with experinece are smaller in number. Also worth noting that those that have done it before you, often did it at their own expense, often working out what does work by trying 19 things that didnt first! Most are loath to give way exact info that came hard learned or finiancilly costly, or more likely both.

The experienced race prep firms, Iain Daniels classic motorsport, or Paul at Evolution GT will know all the answers of course, but they have a living to make, so they would expect your custom (perfectly fair imho)

To move forward and be able to get real world experience answers, you need to decide which camp you fall into, enthusiastic novice wishing to build their own car without Pro help, or someone happy to buy the bits youve asked about from those running prep firms and have the answers.

If the former, there will be those that are competing that will assist, but unlikely to put on an open forum all their hard earned knowlegde, but a phone conversation or emails may get what you need :-)

By all means drop me a PM although im not a GTE expert, all my knowldge and exprience has been with the smaller 4 cylinder cars :D
