Best lowering springs available
What are the best lowering springs available for the Celica in terms of quality/handling/ride? I want to drop it between 30 and 40mm. Local shop recommended Tein or Eibach, but probably only because its what they had in stock.
Price is not really an issue, as long as it doesn't head towards the cost of decent coilovers.
One more thing, how does it effect the cars warranty? Will it just void the warranty with regards to the shocks or will it void the whole warranty. I don't really want to void it because it was the whole reason for me buying a new car. And for the new smell.
