H&R race are low, maybe even borderline slammed. But I wouldn't recommend top hats on the rates they offer. I believe they're 460F/350R

Rates I wish my progress coil-overs had

GC top hats work with GC coilovers and the like, only.

They make use of the extra space at full droop when you have short race springs.

With regular springs, there is no extra space. And they may likely not even fit on, since you'd have to compress the spring on. Its just not made for it.

Correct, but there are plenty of Ebay top hats floating around.

get stock tophats for cheap at local wrecker, get a welder to extend them an inch or 2 with a proper size piece of metal piping.

Just get OEM top hats. There is no need to run extended top hats.

Did you read anything Tyson said?

Extended top hats allow the SHOCK to mount higher and in a better travel range for a lowered car, extended top hats or stock mount in the same place and spring isn't affected at all, your going to have to compress longer springs no matter what to get on either...

They don't allow the shock to mount higher. The allow more room for the shock to extend through without smashing the bump-stop against the OEM top hat. Just gives you another inch or so of suspension travel, but it does not change the placement/position of the shock.

^ What abs0Lut means is the shock rod mounts higher on the taller top hat, and he is correct with his post.

I'm not aware of any lowering spring that is low enough to justify extended top hats.

No. Use the stock top mount. you don't need extended top hats, you aren't even low enough to justify them.
