Bit overkill to be honest.
With the single beam rear axle, and single wishbone fronts, I don't think that the full effect of the advanced damper over the standard BC would be felt.
Something like an RX-7, with double front wishbone and IRS, would probably be brilliant with them, but for a Starlet, I'd stick with the normal BC's.
I have them on my GT, and they are utterly immense!
