LS1 into a Vauxhall Astra Coupe
I have been saying it since post #5....it going to be one sweet ride. The quality of the work, the dedication, the pace, updating this page.......all good stuff Pete. Keep it up mate.Can't wait for the video.
Thanks again for the encouraging comments guys

Can't tell for sure, but from the pics on page 17, it looks like the chassis is already pretty stiff. It appears that there is a front section of channel in the bay that is tied to a channel running under the car. From there, I recall a rollcage (a piece of art!) tying from this structure to the rear subframe of the car. If I recall, from somewhere in the page2 or 3 of this thread, Pete built up the independant rear and tied it to another structure that crossed the rear subframe channels together as well. I would bet this car isn't prone to flexing...

They are like chassis legs that link front and rear cradles from what I gather.
Although being caged etc....cant see they would offer much benefit for the work required to install/build.

The blue bit bolts to the O.E engine mounts on the chassis members both sides, and the cross bracing is bolted to it and the subframe, and is on polybushes both top and bottom.
On some cars, it really makes a difference. F-bodies in particular are very prone to flexing, and the sub-frame connectors tie the front and rear subframes together like a perimiter frame.

But the addition of a rollcage wil massively strengthen the shell again. So lessen any need for the likes of subframe connectors.
By comparison...most big US cars tend to be rather wobbly.
Euro spec cars need stiff solid chassis, as it helps safety, handling, comfort, everything, and how cars handle is a major thing over here. If they were all big soft wobbly cars that didnt handle, nobody would buy them. We have crap roads, with lots of bends here...
As Stevie says, the chassis is solid, from front to rear, the subframe is removeable and carries the engine, steering rack and ARB.
On the standard coupe, the rear beam axle was bolted directly to the chassis.
And to answer chevysaab, I haven`t spent £8000 ($16,000) yet. The drivetrain from the GTO was £2335 ($4670) and I sold my eng / gbox for £2500 ($5000) and have sold various other bits along the way to susidise the new parts.
