How do i stiffen body roll in a 1987 supra?

The car is 24 years old and while it may well still go like s**t off a shovel if you are getting body roll the present springs and shock absorbers and anti-roll bar bushes are probably long past replacement time. I recently replaced front and rear springs and shock absorbers on my wifes 8 year old estate car and was amazed at the difference in the handling. You should be able to get aftermarket springs and shocks all round for a fairly reasonable price from internet suppliers and anti-roll bar bushes from your local motor factors or, again, internet traders. The total cost will be less than the price of a set of new tyres.
