H&R Race Springs, No isolators at all. Ride feels relatively stock. UPR Caster/camber plates. Still awaiting alignment. Work done yesterday.

H&R's website lists the Race Springs for HT only. They work on vert's as well?
Same amount of lowering or different?
The site also recommends upgraded shocks/struts. Are people doing this or keeping the stock parts?

The stock shocks are fine on the Terminator. I believe the verts are a little heavier so require a different spring in the rear but I am not 100% on this.

They really lower about the same on the coupe and 'vert. The reason the part numbers are different for the sport spring for coupe/vert is because the vert version has an extra half coil.

For a 'vert with race springs, I'd upgrade your struts to coupe struts at least. Vert stock springs are a LOT softer, and the shocks/struts are valved for that rate.

I have MM CC plates coming in this weekend im replacing with....I am wondering Im not getting the slammed look some of you have got so I was wondering about which ISO's to remove from the front since the fronts will be out for the CC plates, might as well do it......Just wanted yalls opinion on how I can get my front stance lower to get that agressive look

Do yall think it would look funny to remove all the front ISO's if there are MM Iso's in the rear? Or i should swap bottom out with stock ISO? guess im just stuck on what i should do & think my car sits rather high for having H&R SS springs.

Keep the stock iso's they are there for a reason you know. You are going to have some noisey springs without them.

Thats not true my springs make no noise and I have no isos It depends on the car and the springs Hissman had eibachs and said the noise was horrible. How ever I have no noise with my setup.

I'd just pop out the top one. I've never heard any noise from not using them. Sounds will be transmitted through the springs (read: road noise) because they won't be isolated as much, but probably not enough to notice.

I have the Eibach springs (not sure which ones, but I'm guessing they're the earlier model #) and the rear rides a good inch or so higher than the front. How much would the rear drop if I removed the top and bottom isolators?
