I was warned that the road race crew doesn't play well with street car or more casual guys. Guess I needed to find out for myself. So long TMO.

Grant - my main question wasn't about "patching" anything together. Good grief. Just asking if my rear spring rate was appropriate, then I went on to ask if other springs could improve things without ruining ride quality.I'll just call a place this week.We'll call this post: done.

Thanks Rod. It was an interesting read.DaveW: Bilstein HD's. The fronts are BMR 260lb progressive rate. The rears are 2.5", 10" x 200lbs. I chose the rears to start with because BMR pairs a 220lb conventional rear spring (progressive) with it.So here are my questions:1) What is the...

Thanks Guys.I wasn't sure if I should go down in the rear or what.Can you tell me how high you think I would need to go in spring rates front and rear to see measurable improvement on a 43 second course? And... would it make a good thing (ride) bad on the street?My shocks/struts are...

Hey Guys. I'm looking for guidance on an appropriate rear spring rate to match my 260lb front springs on a Solo course. The front spring rate is admittedly low, as I mostly street drive and am concerned that it would be too harsh if I went much higher.I run the adjustable spring perches...

My car is lowered and on 27.2" tires. No issues here.Here's the 2.75" version.https://vibrantperformance.com/catalog/product_info.php?cPath=1527_1032_1055&products_id=4551&osCsid=32f995ed63bfff9c12699deb2859e391

Welded to the exit of the X. They made it a little deeper and quieted it down a noticeable amount. The GT500 axle back was the final piece for quieting it down.

I use these, Vibrant Ultra Quiet resonators, right off of the X. 1-7/8" --> 3" X --> Ultra Quiets --> Borla over axles --> GT500 axle back. It's very quiet, to the point of not waking the family on an early, cold start.

Thanks Guys. I appreciate the kind and funny (Bill!) words. 👍

Thanks. I'm headed to my local store for 16qts tomorrow morning. 👍

Done and done. Thank you. 👍

I'm John Hartman. I've been playing with late model Mustangs since the mid 90's. They have always been drag race based, but street cars first.I've owned my current car since early 2013 and chased dragstrip et's, little by little until I made an 8 second pass in 2018 and stopped chasing...
