To lower or not to lower???

You just missed the part where you remove the stock bump stop and replace it with a low profile poly bump stop. ;-)

I use Energy Suspension 9-9132G. They're .375" tall.



That's also why you need the larger torsion bars. You don't want to be hitting that small of a bump stop all the time, because they are definitely not progressive like the stockers. And if you lower the car that much, your available travel is reduced to a bit more than an inch before you hit even the smaller bump stop, so your wheel rate has to increase accordingly.

On my car, my 1.12" torsion bars have a 300 lb/in wheel rate, which is 3x what the stock wheel rate was. So, I will only use about 1/3 of the suspension travel, which means I can lower the car so my available travel matches what I'll actually be able to use. Stock cars had about 5" of total suspension travel, mine has about 2". But since the wheel rate is so much higher, even if I raised the car to have more travel available I wouldn't ever use it.

I know that you have big torsion bars and low profile bump stops, but you seem to be the only one that does in this thread,all the other must be sitting on the factory rubber stops if they are that low.
Most of the cars I have had the front was only about an inch off the factory bump stop before lowering. I'm a bit surprised that they had 5" of travel stock, I would have guessed about 2"s before they would touch the factory stop.
I'm going to go out to the shop and stick a factory stop on the car and see how tall it is...
