Striker Rebuild
Hi All
I've just bought a Striker that will be used for sprints and hillclimbs (road going class for now). I've not picked it up yet so
don't know the full details.
The car needs a bare chassis rebuild.
When it's stripped, I'm going to take the opportunity to check the chassis for any damage (any obvious cracking points?) and modify if
necessary. I'm new to Strikers although I built a Fury many years ago. I know a front ARB is recommended but are there any other chassis mods
that I should consider. The car is a live axle version with, I think, the modified Escort uprights. The chassis number starts with S90 so I'm
guessing it was a 1990 chassis. It will be running a 1400 K series and Type 9 box. Tyres will be 1A (local race championship requires 1As) or 1Bs. It
may end up on slicks at some point though.
Many thanks in advance.
Wyn

I'm probably not the best person for impartial advice, but I spent on a lot of time on the Striker Yahoo/Google groups so I learned a few things
about them.
The common points for cracking on the Sylva cars are the rear axle mounting brackets on the axle itself. The unusual rear suspension system (a watts
linkage rather than double trailing arms) puts the axle under torsional stress when the body rolls or in one wheel bump. This is why it's
important that the rubber bushes that locate the rear arms are retained and not replaced with spherical joints.

There's a cracking striker/ab arion chassis on piston heads!

Im intrigued now but cant find it. Linky?
Sorry op of you feel toys is being hi jacked. The other things i can recommend are a rear suspension tie to go above the fuel tank and join the upper
suspension mounts, and roller bearing rocker arms.
Track days ARE the best thing since sliced bread, until I get a supercharger that is!

I'm not sure what you mean by the upper suspension mounts?!

I think my brace bar bolts on with the same bolt used to bolt the top of the coil over. I was told it removes known chassis flex at the rear.
Sorry for the lacking detail.

He didn't 'rip off' the Striker, my understand is they are actual Striker chassis. There are new, AB, chassis for this year.

Probably worth replacing your lower locating rods for the box section types as you may end up with this after some spirited launching
Also go through all the rear bushes and check if you have 12mm bolts in 1/2" bushes and resize as necessary

Thanks Jeff. That's removed some confusion!
R1_striker - I don't actually have the car yet - picking it up on Wednesday :-)
Rich - I'll drop you an email in the week - would love to pop and see yours and pick your brains if that would be ok?

Hi
Chassis Mods:-
Check the top wishbone pivot mounts.
Reinforce the steering rack mounting as they can flex.
Other than that it's general wear and tear like any other spaceframe.
Front ARB is a must.
Other mods worth looking at
Move the fuel tank - we used a F2 stockcar tank, moved the passenger side firewall (behind the seat) forward about 50mm, slotted the tank in
vertically behind there - So behind the firewall and still accessible from the 'boot' but in front of the back axle, and the base of it is
at floor level.
Gel battery on it's side under front edge of passenger seat.
Access panel in tunnel to get at gearbox oil filler.
Uprate the Type 9 (BGH or similar) and fit a Quaife gear lever kit - do the latter even if you leave the box alone!
Quaife ATB
Make sure the axle ratio is short enough so it'll rev out in 5th just as it hits the aero wall.
If it's not got a full cage go and see Nigel at Cougar Engineering in Redditch.
Set it up right and it'll be right at the sharp end..

Oh and BTW - yes that is still your old rear wing on the back of the Reynard!

AB used to be an agent for RAW so suggests he was closly linked with them. Its funny as I did spot in some of ABs FB photos that the chassis looked
striker esq, but could never find a full enough picture to be sure.

Thanks Jim
I looked at moving the fuel tank in a Westfield we rebuilt a few years ago to that position but ended up with it in the passenger footwell (suitably
paneled over). I like the idea of the tank in front of the axle.

Rescued attachment fuel tank finished (1).JPG
Gel battery will be in passenger footwell.
I've got a couple of different CWPs for the axle somewhere in my tip of a garage so hopefully I should have something suitable there.
I thought the wing looked familiar :-)

If you want some inspiration, this Striker is fairly local to me and was built for sprinting and hill climbing. A few more details in
this thread.

Definately, it struggles for grip with the tyres he's got!

I got to a point today where I realised staring at the Striker wasn't helping. So I got stuck in!

I couldn't remove the nearside rocker as it appears to be seized to the through bolt? Will have another look tomorrow - pretty cold out there
tonight!
