The Better Bilstein Ebay Coilover Thread
#1643
I got everything swapped in last night. After ~4 years on VMAXX, it's about damn time to run VMINNN. The vmaxx is limited to pretty low ride heights, so I've always ran in the ~4.5" pinch weld range. With this new setup, I'm at 5.5"F/5.75"R, but I have about an inch of sleeve travel available to lower it if desired. At this ride height with these springs, I've got about .5"F/.25"R of unsprung droop that I'm giving up. With 20mm extended top hats, I have a lot of room for long bump stops. I cut the fronts at ~50mm, and the rears at ~55mm. These lengths lifted the car off jacks with no springs and left at least an inch of clearance everywhere. No more melting fender liners. No more scooping up rocks with my butterfly brace. Now I just need to see how much negative camber I can get in the front at this height. With ELBJ's & adjustable RUCA's, I'm pretty confident I should be at least able to hit the 949 street settings at ~-1.4*.

Hi guys,
I am putting together a Bilstein setup for my 1990 NA Miata. I picked up a set of Bilsteins and after doing some research on them they appear to be NA HD shocks. I've already ordered some parts for the build and was wondering if you guys could give me a little guidance. I'm going to go with 450/300 springs for a street oriented setup.
Shocks:
F4-B46-1489-H0 New part number 24-014892
F4-B46-1488-H1 New part number 24-014885
From what I understand these shocks are a little shorter than other shocks. Look at post 8 here for length comparison https://forum.miata.net/vb/showthread.php?t=411554
I picked up allstar springs and sleeves
Picked up 4X extended top hats from TSM with isolators(maybe only need two?) TSM Aluminum Shock Mounts
Plan on getting the integra bumpstops and cutting the top off to use above the top hat. Integra Shocks and Springs 310 3019-50 - Integra Speedthane Shock Bumpers
Plan on getting 4 delrin spring washers. RideTech 70010828 - RideTech Delrin Spring Washers

My question is:
- What do I use between the shock rod and underside of top hat?
- What length springs should I order? I was planning on 7" for front and rear. I realize now that my shocks are somewhat shorter than what most use and I wonder how that will affect performance. Should I continue building these HD's or opt for a longer set?
- Should I plan on using the TSM top hats in the front and rear?

You need shoulder nuts to use NA HDs with NB hats. Seen here.
I have the same shocks and don't use extended hats, still have plenty of travel.
7" springs is fine.
I would also recommend getting them revalved (TSM is who I used), I've heard not-so-great things about stock NA HD valving but never experienced it myself.

I was under the impression the bump stop length and durometer determines how far in the stroke the bump stop begins and how quickly it stops you. The only thing I need to account for is to ensure the shock bottoms out on the bump stop before bottoming internally, correct?

You know, Accura Integra.... got a little confused there as i've read about both stops. I meant Integra bump stops.
