No, a slight increase in harshness. I'm not sure, however, that I'm prepared to accept more harshness by adding springs. I would consider, however, an adjustable coilover system when one becomes available.

I did the conti's. The Yokos are also available in these sizes. 305/25 and 275/30.

let me just say.....

i sure hope you all begin to feel the difference in ride from the decrease in unsprung weight. The pictures, the cars, look great. I personally would be running the 275/30 up front and the 305/25 in the rear. That will not produce any ABS error ( or any other error). It will, as we have discussed, produce a speedo error, erring to the side of saftey for you guys as the speed will be overstated by 4%. On the other hand, I like the free differential upgrade and be sure the 500hp will be quite happy spinning a larger tire.

Beautiful cars, no doubt looking a bit more agressive with the H & R's but all looking much more 'proper' with these wheels.

Just had them mounted today so haven't had much seat time. Did notice a clunking sound when going through my neighborhood road dip and pulling up the garage curb but it doesn't sound like rubbing...more like a light clunk from the right rear...hope it's not something with the spring install...have to get it checked out.
Likely your springs are seating themselves. It is difficult to get them properly seated while the car is in the air. Many times it takes a few mile and a good bump to get them seated. It should go away entirely - if it doesn't let them take a look at that corner as the spring can get hung up. The larger rubber will definitely not rub - it is not even close.

Good choices all the way around. Congrats and enjoy!

Metalman has had Motons on the car for some time. He is actually doing some fine tuning right now regarding droop/shock shaft lengths. Now that he has done the hard part all you have to do is call Moton or email Metalman and you can have full adjustable suspension. He has a set of wheels with 325's mounted on the rears - just wait until you see this set-up.

Running 275/305 Conti's...ride is just a bit stiffer...hardly noticeable. Thanks again to Chuck and Shep for the awesome job with the wheels!

He already has the tires mounted - just waiting for the motons to come back with the redesigned shaft length. He tracks the car often, on slicks, and is not real conservative when it comes to such matters.

no practical way. there are ways to write an algorithm an do a correction electronically, but, the wiring is super involved and ultimately I do not know anyone with a device that is plug and play.

Drove the car out for lunch and did hear the tires rubbing when making a hard right (from left rear). All the clunking and rubbing seems to only come from the left rear so I'm wondering if it might be the springs not set properly on that side. Curious to see if anyone with 305 are larger experiencing and problems...with H&R springs.

Strange considering you guys think there shouldn't be any rubbing...seems like there's still plenty of clearance..
