Hi Everyone-

I want to lower my is350 AWD. I am currently leaning towards the RSR Down Springs. I would love the Half Downs, but they wont work on the AWD. Is there any options outside of Down Springs that will give me a more minimal drop?

Appreciate the insight.

 

I am going to try the half downs on my awd. I don't know why they wouldn't work. I'm thinking I might get a little more drop in front due to the extra weight

 

My understanding in the spring rates are quite different. Causing length issues, and creating odd noises. Just a heads up.

 

i sent you a pm

 

would be curious if you have any insight you could share on this.

 

i dont know much about springs (sorry). i had coils but now i'm bagged

 

Do you know of anyone that has tried this and failed? I know the spring rates are different, but don't know about length issues and odd noises

 

Called RSR and they said the half down springs would physically fit,they advised me not to do it. They said that the ride quality might suffer and since I have aftermarket rims they couldn't guarantee there would be no problems. Down springs for AWD was their solution which gives more of a drop than what I want(afraid of rubbing) want, so I guess I won't lower the car after all.

 

here's a photo of my buddy's IS350 AWD f-sport on RSR super downs, my GS350 is on the same RSR super down springs.

the rears do sag a little more than the front but you get a noticeable drop, not much stiffer of a ride

 

what size rims and tires are you running?

 

19" Vossen CVTs,235-35 front 265-30 rear

 

i would think you would be ok with downs
