The Rally springs are definitely more expensive than when giwu42 first started his post but cheaper than when the rear B springs were first released.
here is from my records
| Part Number | Part Name | Price | Quantity | Total |
|---|---|---|---|---|
| RK9Z-5310-A | Spring Front | $80.13 | 2 | $160.26 |
Subtotal: $160.26 |
Estimated Shipping to 94044 via Standard Shipping: $20.64 |
Total: $180.90 |
That matches what my subtotal was in Nov. My final total was $427.18 after all was said and done.
my total was $464 after shipping and tax... i'm hoping around $500 for the install for a $1000 total for the change. looking forward to the comfy ride, while still maintaining flat cornering with the magneride and eibach bars. should be arriving early next week.
Looking forward to your review.
Definitely put in the part number and never enter in your cars info especially the VIN. I order these springs from them all the time and never have had an issue but I know others that have added their car’s info and have had issues.good news and bad news.
bad news first:
i was sent 2 sets of rear springs. tasca had both 1) a larger blue ford heading label 5310-A (front spring) and 2) small tag with qr code and 5560-ABC (rear spring) attached to the springs.
i honestly didn't even notice the smaller tags since on cursory check of the larger blue ford labels, it looked like i was shipped two 5310-A and two 5560-ABC springs. what a pain and waste of time to have to deal with a return and potentially another trip back to the shop.
good news:
despite not having the correct fronts, the shop did install the rear springs and boy has the ride quality improved significantly! to use an overused phrase, it should have come from the factory this way!
i've always thought the mach-e had a stiff-legged ride. magneride improved/resolved the rear "bouncy" nature that existed to small degree on my premium RWD, but it still rode very stiff legged especially over small-medium bumps, especially noticeable at slow-medium speeds. in fact, i always belt magneride was best at faster speeds when the amount of travel was less critical.
not sure if ford did this purposefully for aero/battery-saving reasons... or just mis-judged how much the weight of the battery/car would use up minimal spring heights. either way, the car actually rides like a car now, rather than a truck.
driving back from shop on the pot-holed streets of LA, it's remarkable how 1" of additional rear travel alone really lets the shocks do their thing to absorb the small to mid size bumps. the eibach sway bars still keeps cornering flat.
debating even bothering with the fronts. you can tell the rear tire gap is slightly greater than the front if you look carefully. but since there's already a decent gap in the front it's not as noticeable as if this was a partially lowered car.
for now i'm waiting to hear back from tasca about about getting these extra rear springs returned and refunded.
if i do decide to order the front springs again, should i just do what i did last time and put in the part# again and hope they get it right this time?
or is it better to select by model and choose "2025 - ford - mach e- rally" and go into the rally parts catalog and pick out the front springs that way? is that safer?
Yes going from 228 spring rate to 183 is a fairly decent change. You will notice a difference but won’t be as great as the rear.
I did not tell the service writer that I had lowered the car. The shop noticed it independently. By way of update, though, the BlueCruise issue has resolved itself. A tech at my suspension shop told me that he has done mods on Teslas which caused an initial issue with the self driving but those resolved after a few drives. So maybe these systems have some compensation capability. It seems like they would have to be flexible for the reasons you mentioned, like loading. By the way, I totally agree that dealer service writers will invent excuses not to work on a car. That's why I didn't tell them in the first place. I was actually impressed that they noticed the lowering. The module destruction just has to be BS.
