Rear Coils

I am replacing the rear coil springs in my car. I am looking at some TRW rear springs which they sell at advance auto parts. Has anybody here used these springs and if they have do they like them?Will they raise my back end any, and if i get the heavy duty ones make the back end sag so much when I have a car full of people or cargo in what trunk these cars have?

Don't know about the TRW coils. I have heard good things about Moog and others. For more info, read this and follow the link.

Yes they are the same. Those brand names both belong to Federal-Mogul now.

The part # you want is CC635 IIRC.
