Which coilovers to choose

[Tiger]

Hi all,

I need some coilovers for my 1968 Chevelle to be used with the Corvette C4 front and rear suspension.
I am thinking about the single adjustable Koni aluminum coilovers that Summit and Jegs sells.
Does anyone have any idea if these are good or bad?
Should I get something else?
Any links?

Thanks!
André
