Bumpstop Problems

[5.0Moe]

So i have H&R SS Springs installed. 1.7" drop in the front 2.4" in the rear. I also have BMR LCA's and UCA/ Bracket installed with the pinion angle adjusted properly. When I installed my springs i cut the top half of my bump stops off for clearance. The problem is that I still only have about 3/4" suspension travel before the bump stops make contact. Does anyone know of aftermarket bump stops or if there is another route I can go to get some more clearance?

Sorry about the pic, its the best one I could get peeking through the wheel.

Cut them again.

These were the bumpstops supplied by Ford with my Boss T springs.

Excuse the potato quality of the photo.

thanks for the info! Im going to cut them down to that height and see where that leaves me.

That is not really that bad. Some cars are designed to ride the bump stops at ride height.

Yeah I wasnt worried when I installed everything but these bump stops are so hard. I bottom out on any decently sized bump that my rear hits. Maybe softer material bump stops would work

Pick up some FRPP ones and cut them. They are made of a softer material.

I actually lowerd my car with steeda springs and added 1/2" nylon plate to make my bump stops taller.. this was to help stop rear end sag. i fixed the rear end sag under acceleration issue by adding a set of BMR control arm relocation brackets. thatks for the reminder now i'm going to get those spacers removed i only have about 1/2" of air gap between jounce bumper and body of the car at curb weight.

FYI I experimented with reduced height jounce bumpers last year.. I also had my rear suspension setup for 'pro squat' . no anti-squat in the rear what so ever. Result? the car squatted so hard on launch along with a huge twist of the axle forward that it smacked the upper control arm bracket area against stamped sheet metal bottom of the car! - Loud boom, and another louder boom when I grabbed second super hard.

Soon as I reduced the pro-squat problem solved. so you can add some anti squat to keep the rear from needing to make contact w/ the bumper so much...

The H&R Springs are very stiff, my car doesn't squat under acceleration. The problem was solved that a couple people have commented on already. The smaller FRPP Bump stops are also softer and don't make hard contact when the suspension travels. I will update the thread once I put those in, but other people are saying that it is the proper fix. After all, they do come on the boss and gt500

I am pretty certain the FRPP were the same height as the OEM stops, just a softer material. This is going by recollection from a couple of years ago but I still chopped off the top piece to give adequate spacing.

Thats what I figured, still going to cut them to the lowest point like "mycroft" posted
