The beleaguered Prost and Williams teams both hope to have revised cars on
the grid for forthcoming grands prix.

The Prost AP01 - the first car to bear the initials of team owner Alain
Prost - has been diagnosed as having a major rear suspension problem,
prompting the team to undertake a complete redesign of the current set-up.
It is also considering introducing a longer wheelbase version of the car -
a route already followed by both Williams and Jordan - in time for the
French GP, when Peugeot hopes to debut its latest engine.

Williams may have to wait less time for their modifications, but do not
expect to have them ready before the long haul trip to Canada. Again, the
rear suspension is under investigation, but the team face tackling Monaco
with little change from Barcelona, where it suffered its worst grid
positions for 1989.

Ferrari, meanwhile, are due to introduce a new front wing assembly in
Canada, hoping that this, along with improved Goodyear tyres and its
radical exhaust system, will bring it closer to McLaren.
