Do the sedan is250 springs work on the is250c? Just wanted more options other then the 1 inch lexus fsport drop, thanks.

 

I wouldn't do it. According to the f-sport website, they use different size coils, drop it at different rates, and have different springs rates.

Combined with the fact that the vert also has specific f-sport shocks vs the other models, I'm thinking that anything but a kit designed specifically for the vert may be a bad idea.

If you're thinking springs now, I'd say just do the f-sports. If you're thinking about other options, I guess we gotta continue waiting to see what the aftermarket's going to come out with, if anything

 

Well coilovers will always work :/ I am shocked that no companies have came out with a set of springs...Im sure the f-sports keep the stock ride but the drop is a big weak. JaxISC has some fsports on 19s and although it looks good, it isn't low enough for my taste. Do you think if I got 20's & fsports that it would fill the gap a little more?

 

I personally wouldn't trust coilovers right now either for the same reasons I already mentioned.......unless you get custom spring rates, and even at that I still don't know if I'd want to be the guinea pig.

In terms of 20's and f-sports.....it'll probably make it worse cause the wheel will look big.

 

Yes I understand you want a lower drop on the IS-C than the F-Sports provide. Do you care about ride quality and handling or is that secondary?

 

Agreed because the short tire sidewall makes the wheelgap seem larger.
