I'll have to look into their explanation specifically but I can't see how helper springs will affect ride quality at all unless they are doing something unusual.
@nefariousracing here's what they told me: the helper springs will give you more travel and droop. It will help keep the tire in contact with the road and provide better handling and comfort on rough surfaces.
@@matsudakodo I'd be amazed if you felt a change in comfort, but they can help with additional stroke which can help with handling, but only if the rest of the coilover is designed to have the longer stroke length to match. Just throwing helper springs on by itself won't do that. So depends how their coilovers are engineered and made.
I discovered that, due to a certain mod I made on the car, the rear helper springs get in the way of the drive shafts. On my "fixed height" coilovers, if I raise the lower perch 2-3" to get the helper out of the way (of the shaft) will it lift the ride height? In other words, what's the difference if the helper is maybe 4 inches long vs 0 inches long (fully compressed)?
Yes it will raise the car. The helper is fully compressed under the weight of the car, which means you can only lift the perch by the amount of the fully compressed helper and not raise the car, which is probably about half an inch.
I have ohlins street and track. Currently when I go over bumps or take a sharp turn the wheels touch the fender liner. It did not do this previously even when it was lower than it is now. What could be the cause?
Possible causes I can think of: - Wheels or tyres changed (I assume not since you didn't mention it) - Fender liner itself has dropped - Dampers are set to softer - Your springs are sagging (least likely)
Nice video !! Thx for explaining
You're welcome
Thanks for the explanation. I see some coilovers advertised with helper springs to improve ride quality (Ceika). What are your thoughts on that?

@nefariousracing I agree
