Striker roll bar
cornish striker - 6/10/15 at 07:45 AM

Hi I have a Sylva Striker that was built in '91. I've just started competing in sprints and hillclimbs with it.

I seem to remember that the Striker roll bar has been RAC approved for Motorsport can anybody confirm this?

Many thanks Nathan

It is unlikely that a '91 Striker rollbar is MSA approved today. You need to refer to K.1.6.1 in the Blue Book and see if you rollbar meets K1 or K2 specification.

Rac 'approval' doesn't exist. The term is applied to a roll bar that meets the standards required in the MSA bluebook (previously RACMSA)

Thanks for the replies. It seems that the design meets the diagrams in the blue book. However the diameter of the the tube on the car is 38mm, the blue book states that it should be 45mm unless the roll bar was approved before 1995 which means 38mm is acceptable.

Thanks Nathan.

I suspect to be accepted you would need an MSA log book signed off by a scrutineer for the car to prove it was used before that date. A call to msa might br needed.
Also, more importantly, I would want a rollbar to meet the current standards anyway, theres a no doubt a good reason why they want them to larger sizes!

I assumed this was a road-going car so wouldn't have a log book.

Yes I understand what you're saying regarding roll bar diameter but on some events this year I've seen new homologated cages fitted to Westfields with 38mm bars so it's all a bit confusing. I'm competing in my last event for the year this weekend so I'll have a word with the scrutineers. I just wanted to try and get any info. I could.

Many Thanks. Nathan

There are two systems of approval going on here.

1. ROPS (rollbar or cage) which is built exactly to the Blue Book (K.1.6.1/K.1.6.2) and is therefore allowed
2. ROPS which has been tested/certified/Homologated/Approved by the MSA (hence the 38mm Westfield cage)

unless you can find an approved ROPS from a supplier for your vehicle you are left with option 1

Ah I see, with regard to option 2 bearing in mind the the roll bar on my Sylva was 'factory supplied' with the chassis, and the history that the Striker has in motorsport does anybody know if the Sylva roll bar has ever been Approved by the MSA in the past ?

As I said....very unlikely. But speak to Jeremy if you want to confirm.

Rops approval is an expensive process, so few do it. Procomp are the only kit manufacturer I know of who do.
Sylva didnt and raw don't have one.
Ones that do have a certificate/approval number fixed to them.
I also believe its only in recent years its been available. I doubt it stretches back to 92.
