Today I fitted my Ultra Racing strut brace which I got on special from the NZ stockists - they've probably had it for a couple of years now - paid $135 plus reasonable charge from Tauranga. Actually I paid $315 in total and got the under-subframe brace as well. The middle lower bar has been added to their next order.
I had concerns about whether the strut brace would fit the V6 and sure enough, it didn't get very close at all - about 10cm from the mounting holes on the left side. Preventing it from fitting on my 2002 phase-2 was the ECU and its plugs, the box of connectors behind the engine, the fuses and relays near the coolant tank, and the two pipes on the back of the plenum chamber (one for the brake servo, the other for something unidentified as yet).
The last difficulty is probably the worst and I expect the plastic brake servo hose pipe fitting will break off at some point. That won't really matter, will just make the braking more exciting
I mounted the ECU on two strips of meccano (perforated steel that comes with central lock kits, electrical antennae, etc.) with a couple of nuts, bolts, and washers. One of the studs needs to be hacksawed off the plenum, otherwise it hits the brace. Grounding for the ECU is possibly important, which is why I used the steel strips, but there is enough space to fit it on an angle behind the engine.
The box of connectors can be unscrewed, taken off, turned around, and left to hang around - I might add some Velcro to keep it in place.
The fuses/relays can be unclipped and left to hang around as well - there's still space for them.
The original strut bolts can be used to secure the brace, as the washers are various different sizes.
Did it make a difference? Hard to say, probably not really - of course, you want it to make a difference though, so it might - it's a lot like one of those dreamcatcher things
