1 reason 16" tires on ACR - SRT Forums

Johnny Rocket · 07-13-2005, 07:46 AM

Found this on http://en.wikipedia.org/wiki/Dodge_Neon : The 2004 and 2005 SRT-4 model also has a standard limited slip differential fitted to its beefy 5-speed NVG transaxle originally designed for Graz-built turbodiesel minivans. Unfortunately, the modifications required to fit the 17" roling stock required suspension alterations that limited suspension travel; this was finally cured with the introduction of a 2005-1/2 SRT-4 ACR model.

I don't understand that. I'm running 16" on my non-ACR and they're great... no problems. No reason they couldn't have put 16's on it from the start.

I'll tell you the one reason the SRT4 was designed and built with 17's - bling. It's what the market wanted for show. We all knew 16's would function better, but the 17's helped sell the car. I didn't agree with this decision at the time, but now I understand, and think it was the right decision.

i wish they made reproductions of the stock 17s in an 8inch wide. i would buy them SO fast.

Ditto. I love the stock wheels, just not the width.

BBS VZ's(I think they are VZ's) look very similar to stock wheels, and they are 7.5" wide. But VERY expensive.

Or find some TSW VX1's like I did... they were the wheels on the concept SRT-4.

BBS VZ's have been by dream wheel even on my last car.

It sounds like some engineer was focused on fitting the car with 17's, probably because like someone said, it looks better with less gap. To get the "look", it states suspension travel had to be limited probably to avoid tire rub on the body. It appears what was cured with the introduction of the ACR was the limited suspension travel. I would guess the suspension travel was increased. So, if 17's were put in the place of 16's on the ACR, tire rub could come in to play...

the reason the acr has 16s instead of 17s is the spring perch is lowered meaning you cant fit regular srt height tires on; also to get a wider tire/wheel while still conforming to DCx guidelines for clearances. the physical spring is the same on the two cars also. the spring perch has no effect on the suspension travel on our cars. we have a long travel suspension (ever seen a pic of a corner fully compressed, and seen how much droop the suspension has when you jack up a corner?) so that stuff on wiki doesn't make sense.

I have a feeling it was a money thing...They wanted brand name wider rim without jacking up of price of the acr's sticker...17s wouldn't make the budget...

If you match the 16" acr tire's overall diameter and width to a 17 tire you get a 225/40-17 tires...The 17" tire will out handle a 16" tire because there's less sidewall flex...

Generally a 17 rim/tire combo weighs more than a 16" combo...However an ACRs rim weighs 19lbs...That's lighter than a standard SRT-4 rim, but not considered lightweight at all...

The best mod I have ever done to my car is get 15lbs wheels and 235 45 17 tires...

exactly how many 225/40-17 UHP tires are there? only one that I've found is nitto and those would never make it as an OEM tire. Also, almost every lightweight wheel will not make the durability ratings that OEM wheels must have.

The reason why the ACR has 16" rims is because the ACR model is designed for SCCA racers and 16" rims are the biggest allowed in the car's driving class.

You just owned this entire thread, lol...

stowaway · 08-01-2005, 09:42 AM

its not that its the biggest rim allowed, its that you must keep the stock size rim. a 17x7 wheel would achieve the same thing for most autocrossers (wider tire selection compared to 16s, usually).

I agree that they are rare...
