Here you can see the higher rack position and additional brace of the Mega S2K chassis.

As he said, the holes in the steering arms are tapered for the track rod ends.

 

 

Yes, I'd totally forgotten that!

So, is it possible to weld a bar and brackets onto an older Westfield chassis to raise the steering rack and reduce bump steer?

I wasn’t really aware how poor the front-end geometry was on the older Westfield chassis — in my case, the Aerorace, and also an older road-going version (although on the road, it’s not such an issue). I always thought the handling quirks were just part of the "kit car character" — until I had the chance to drive an MNR VortX Inboard on track, with similar power.

The MNR, designed by race driver Marc Nordon, is a completely different experience. While the Westfield feels like an evolution of an affordable road-going kit car — and you can feel that in its behavior — the VortX is much more composed and confidence-inspiring, especially over bumps and curbs. The difference was night and day.

Now I’m wondering if bump steer is the main issue here. It’s interesting that Westfield changed the design on their newer chassis to a higher-mounted rack. If that’s the case, and the steering rack position really makes that much of a difference, then welding a bar and brackets to reposition it doesn’t seem like such a complicated modification — at least not if it brings the handling closer to what the MNR delivers.

Has anyone here done this mod on an older chassis? Would love to hear thoughts or some guide how high is this bar welded ?

The chassis re-working for the. Mega S2000 was contracted out to Randle Engineering, who are behind the subtle and not so subtle tweaks and changes to the design. Which was then (initially) manufactured in-house, alongside the other chassis offered, before being made, again, like their other chassis, by an outside contractor - it was Caged, though not sure if they carried on after the factory reopened, or not.

 

(the design changes for the Sport 250 were added to the Mega S2000 chassis in house by the old WSC factory, as far as I know).

 

As a general note, be very careful with chassis mods affecting suspension or steering pick up point locations. Make sure you comply with any local legislation. And if the car is for competition, make sure changing these things is ok in the rigs for whatever series you compete in. (It often isn’t.)

 

In the UK, (not for Westfields AFAIK), but in off road circles, a lot of Land Rover/Range Rover custom hybrids lost their VIN numbers under DVSA crack downs, and I know of at least one Caterham that ended up loosing its vin number and having to be parted out and (I think) the chassis destroyed, for the same reason.
