Topless69GT 28 Report post Posted August 28, 2017 Who has the grab a trak mustang suspension kit from Mustangs plus? I am looking to improve the suspension on my Mustang but don't want to spend thousands of dollars for a coil over system. I'm looking at the grab a trak system and wondering how that's any different from the stock set up? My current suspension was a stock kit from NPD. It creaks and pops all the time. Sounds terrible so it has to go. I don't want to spend more than $1,000. Any suggestions? Quote Share this post Link to post Share on other sites
1969_Mach1 333 Report post Posted August 28, 2017 I have their 5 leaf mid eye rear leaf springs and their 600 lb/inch front coil springs. I'm happy with them. You should find out what is creaking and popping on your suspension. Could be upper control arms need grease. If the kit came with stock rubber upper coil spring insulators, stronger than stock springs tend to wear through them and you get a metal to metal condition at the top of the coil spring. If rubber bushing parts like on the lower control arms and rear leaf springs were tightened before the car was on the ground, that could cause creaking and popping. Cracked shock towers will cause strange creaking and popping noises. I've had bad shocks cause popping noises. Try to find the problem before spending a lot more money.

Topless69GT 28 Report post Posted August 28, 2017 I think my spring perches are the culprit. It also appears the springs are catching on the bolt on outer shock tower covers. Those are reproductions and don't seem to fit well. Quote Share this post Link to post Share on other sites
1969_Mach1 333 Report post Posted August 28, 2017 I had new OEM Ford springs perches in my car for some time. No issues with them. But I replaced them with the Scott Drake spring perches that have the elastomer bushings that allow free rotation. The quality seems fairly good. Roller perches, in my mind, are not worth the high cost for a street driving car. https://www.summitracing.com/parts/sdk-c4dz3388hp/overview/ Quote Share this post Link to post Share on other sites

TexasEd 188 Report post Posted August 29, 2017 You could also go with the roller bearing spring perches from Open Tracker http://opentrackerracing.com/product/roller-spring-perches/ Quote Share this post Link to post Share on other sites
