RS-R Down Sus lowering springs

[gramsnacks]

I didn't really see anyone posting or running these on the forums. I wanted to give them a shot for their even ~1'" drop F/R with spring rates similar to Eibach, and I also like their products for the Skyline GT-R.

Spring Rate: 5.61 kg/mm (front), 5.10 kg/mm (rear)
Drop: Front -20mm to -25mm | Rear -25mm to -30mm

I ordered these from Hybrid Racing on Monday afternoon and they arrived Tuesday afternoon - comically fast shipping. Install was super easy, a friend and I were able to take our time with the front driver's side and wrapped the whole project up in ~2.5 hours. As of posting this thread, I've paired the springs with 15mm spacers on the OEM wheels.

Initial driving impressions:
- Rides great in all suspension dampening settings. Great on back road, great on freeway
- A tiny bit softer than OEM I think
- A tiny bit bouncier than OEM
- Doesn't feel stiff whatsoever
- Perfect ride height

All in all, awesome experience so far and I'd encourage people shopping the Eibach springs who want a more even drop from front to rear (ie. no rake) to give these a shot.

Bonus sticker pic. I'm not a sticker person but this is an A+ sticker.

Had them on my 10th gen. Chose them over the other brands just so I could get that sticker. Going to be trying out the Tanabe offering for the FL5...eventually.

Looks awesome! Seems like the perfect amount of drop. This is how I’d imagine I would want my ride height on coilovers.

The drop amount is just right for a daily IMO. Not too low where you're constantly worried about possibly hitting things, yet still low enough where it can look real flossy with the right wheel fitment.

Small update since I made the OP. Swapped out the OEM wheels and spacers for a set of 18x9.5 et38 Rota Grids wearing 275/35 Conti EC Sport02s. Rides really really nice now with the smaller wheel diameter and larger sidewall combined with the RSR Springs.

Good choice, these are also one of the only lowering springs that include bump stops, so you dont have to cut the OEM ones like others require.
