HKS HiperMax Touring Spring Kit

[Supraboi7]

Excited to take care of the wheel gap with a modest drop while still retaining the factory adaptive suspension that the KW V3 kit would delete!!! Looks to be available next month or so, just a heads up.

Thank you for posting this! Im looking towards getting rid of the wheel gap as well! Im hoping someone puts them on sooner than later and reviews them. Interested in knowing if it rides like factory or stiffer? I prefer stiffer over bouncy. I wonder if rear toe arms and front camber plates will be needed to get the alignment back to stock-ish.

Inflated pricing for the sleeve kit, this set up shouldn’t be more than 600.00 USD. But I’ll have to sit on this see how important this is to me

Nice pics! Do you know how much it's lowered by front/rear? I'm considering the HKS springs at some point but don't want to go too low because speed bumps... That height looks pretty good!

Its 1-inch drop all around.

They are adjustable within a range:

• Front Height Adjustment: -25 to -45mm
• Rear Height Adjustment: 0 to -50mm
• Front Spring Rate: 42.6 N/mm
• Rear Spring Rate: 116.8 N/mm

Just want to confirm that these will not throw any codes?

FYI link is not working.

 

[trakday]

will these throw any codes? I know they are a sleeve kit but still with todays computer nonsense.

 

[Vegas Supra]

No Codes would be thrown, You would be leaving the Active Dampers installed and the sensors for those would be unmodified - Speed Industry has 5 sets left

Installed these on mine the other day. Definitely no codes thrown (as others have explained, you're not touching any electronics).

Note that the instructions do tell you to cut off one of the parts of the factory bump stop though, which is not something I was aware of when buying them. Not the end of the world as its only a bit of foam like material and I'm sure you could buy a replacement stock one pretty easily if for some reason you ever wanted to put it all back to stock.

Bump stop before:

Bump stop after:

Anyway, first impressions:

Very little change to the overall ride quality. Can't really tell any difference from stock when driving it on the road (even on bumpy back roads and drifting it round roundabouts in the rain - felt just like before). I'll be taking it to the track this weekend though so will see how it handles there.

One thing I have noticed is that I'm really struggling to change the ride height now they are on the car. On the front I can't even get the locking collar to undo and on the rear once I got the locking collar undone, the whole threaded assembly just spins as I try to turn the height adjustment perch. This is with it up on a lift and the suspension is at full droop, but I'm thinking the springs are probably still putting a bit of pressure on the perches so will try putting some spring clamps on them soon to relieve the tension then try again.

Thank you @ChrisD for the review!! Question for you, what did you do when you reached the step pictured? Did you just take a chisel or pry bar? Did you use a special tool? Thanks again!
