I'm interested in this topic.
I haven't built a streamliner yet, but have built a handful of successful FWD racecars, including two Production Supercharged FWD cars that were almost stock, chassis-wise, and were very driveable and stable up to 230 mph (so far). I expect our current car, which weighs 3400 on the starting line, will eclipse 250 mph, with exclusively OEM suspension components, aside from adjustable coilover damper units.
And, an open diff.
