Coilover options for i4

[Evan]

I’ve been looking but can’t seem to find any available coilover options for my i4. I’ve contacted Nitron but they’re yet to start development. Any other suggestions?

Thanks so much!

Jubu has Ohlins for i4.

JUBU spec Ohlins TTX suspension road & sport (2-way)… PURE ART

Figured might as well do it right the first time. In my Alfa 4C, went with KW 2-ways as an early adopter when they were first released. More coilover development happened over the next years making me FOMO. Lol. So decided to just do it right the first time with the Emira. The Emria stock...

If anyone gets an update on availability of the Nitron NTR Fastroad 1-Way Coilovers, please update this thread.

Appreciate it!

Weird, I emailed them back in January and they said they were finishing up development of their electron r1 and r3 kits. I would assume non electron would be easier or the first to be developed. They were even asking if I wanted to pre order the kit.

Contacted Nitron today and got this response back:

"Thanks for reaching out. We expect the Emira I4 kit to be released within the next couple of months. Stay tuned to our website or your favorite Nitron Suspension dealer for a press release."

I inquired specifically about the NTR R1 Fastroad 1 Way 40MM Coilover Kit.

Any idea what the difference is between I4 and V6 springs/shocks design? The front hardware is the same AFAIK, it’s only the rear that may have some small differences.

There's no difference in design, it's the spring and rebound rates that are different and take time to develop both on a bench suspension dyno as well as road testing.

Thanks for the reply, I figured the hardware was basically the same but thanks for confirming it

Ok, understood, but the difference between the models is hardly a big difference IMO. The models basically weigh the same and have the same weight distribution (near as damnit) so why would they need significantly different spring rates or (adjustable) damping? (No expert on the matter, just doesn’t make much sense).

 

[F1 SML8R]

Well, if Lotus is even changing spring rates amongst the same model (i.e., Touring has a couple of different spring rates amongst the V6 Touring model per posts on this forum), it tells me the suspension tuning is a bit more complicated than we think. Hopefully, Nitron get something done soon for the i4.

Remember the rear subframes are different (obviously) since they carry different engines and weights, even the rear wheels and offests are different between the V6 and I4...but we are assuming the delay and extended length in development has some linear relationship to the complexity of solving the problem, which may be the case. But it also may be the case that, they are just busy with other stuff...or the doner research car didn't come in time, or something not related to the development of the suspension is affecting this timeline, or they are pointing their finite resources somewhere else with a bigger market, etc. 2 months away is very close so that's good news

Valid point, forgot about the rear-subframe difference. The mounting hardware for the rears would definitely be different.
