For those who have them or are familiar with them, do the install instructions require the bump stops to be cut?

Thanks in advance.

 

No, you leave them as is.

 

Thanks for the info!

 

I have the titanium half downs on my car, the ride quality and handling are amazing too.

 

to add another question to this...
With the springs what is the advantage of doing the springs over say new coil overs?

 

The springs cost a lot less. $250 plus install and alignment.

Coilovers are >$1000 plus install and alignment.

 

Since the springs are made to work with Stock Coils, are they good on performance, Ride etc...?

If you had your choice, what would you do?

Im typically really picky about what I put on my car. I had a STI that had springs that I was not very happy with. The ride completely changed.

Thank you for your input...

 

If $$ wasn't an issue I'd go with AVS compatible coilovers for their adjustability. But then again, if money wasn't an issue I'd probably have a more expensive car with alot more performance to begin with!

I'm going with the RSR half downs springs because I believe they strike the best balance between comfort handling and looks at a good price. Would I like it a little lower? Sure, but I don't want to sacrifice much in ride quality. The spring rates on the half downs are a little softer than the similar Tein H-techs so the ride should be better. My previous car (Acura TL 6MT) had H-techs and it was just right for me.

 

For those with half downs or downs, how well does your variable suspension setting work? Any problems or hiccups in sport or sport + mode?

 

Generally, minimal drop with right spring rates on a springs would give you slight performance advantage without sacrificing comfort and reliability. But dont expect it to do good on the track. Coilovers would give you fully adjustable height and stiffness for maximum performance (with decent brand coilovers) however you do sacrifce lot of the comfort aspect of the vehicle. There are brands like ohlins who designs their coilover both comfort and track performance with dual valves system in one design which can cost upwards of $3k. Also you can run wider wheels (hellflush or performance stand point) with coilovers since they tend to be more narrower than springs.
Personally, if it wasn't for the variable suspension on f sports, i would buy a coilover set. You just have lot more options with coilovers for both performance and looks and many company's have very affordable rebuild program on their coilovers. But i would like to utilize variable suspension feature since it is my DD.

 

No issues that I'm aware of with half downs. I use all modes just about every day.
