If you call 1.75 and 1.25 inches "lowered", then the IPD springs will be fine for you.
I still consider that 4x4 ride height.
If you, like me, think that is 4x4 ride height then your options are as follows...
Cheapest:
Cut springs - Damn near free and
when done right still rides great and handles 100% better than stock.
Towery's budget coil-overs - very cheap way of getting a decent performance suspension on a 240 and really hard to argue with it's results, tunability or cost.
Not cheap:
RSI or Kaplhenke Coil-overs - they have done all the work for you. Parts that were intended for this purpose. Peace of mind, less aggravation and someone to call to ask questions while installing them.
Expensive:
RSI or Kaplhenke Lowered Coil-overs - Able to go super low and still ride decently. Tested coil-overs on race and auto-x cars that actually work. Both can be geared to a street car with softer springs/dampners.
Your advice wasn't too bad except for this part where you obviously have limited or no experience when it come's to 240's. Mis-information is worse than not saying anything at all. Think about that next time you speak of something you know little about.
