Awesome, all the more reason to keep it!

The best reason I can think to get rid of it is the weight...the trunk/wing weighs a ridiculous amount.

They make those for the X but I've never liked the looks of them. The 8/9 and the X have different roof-lines though.

LOL ouch! It's carbon fiber though

They say that Star Specs run wide. Since I only went with 9.5" rims I decided to play it safe and ordered 265/35/18 instead of 275s.

I'm going out on vacation from the 9-18th. The plan is to get the tires mounted on the rims in the AM on the 19th, pick up the head at MAP, and then run them both over to DB.

I don't see a point in dynoing on Winter tires since there seems to be some question about how they affect results.

**Murlo26** · 04-06-2010

Good choice.. winter tires seem to be the suck at dynoing.

Ps. My 275's might have possibly come in today...and they might possibly be getting mounted today at 4:30 and on the car...hehehe

Monster truck ftw!

**scheides** · 04-06-2010

Winter tires seem to suck up about 10-15whp, so yea, def get the summers on there.

**Kracka** · 04-06-2010

Star Specs are heavy tires, especially that large of ones. Compare the weights on TireRack vs. your snow tires. Good call on getting it all setup in summer trim for dynoing though.

Not sure if my bathroom scale would be accurate but maybe I'll weigh them both for giggles. The Winters are 245's since I didn't go smaller than stock and the new rims are lighter.

**Murlo26** · 04-06-2010

Yup, gonna look monster truckish for sure, lol. But at least i will get some grip back

I looked at the weights of rims and tires on tire rack i think i picked up 2lbs per tire/wheel (since rpf1's saved me some).

Gonna have to go 2 piece rotors I guess to balance that shit out

But my winter tires are heavy too.

I never would have thought lighter tires and rims would make such a difference on a dyno! That is just crazy.

**Kracka** · 04-06-2010

TireRack lists the weight for most tires and wheel weights are easy enough to find.

**Murlo26** · 04-06-2010

Well I think my rims are 2 lbs lighter than stock...so I picked up 4 lbs per rim/tire over my OEM summer tire/wheel.

Kind of a lot, but who knows, I guess we will see what happens next week. Star specs are 32lbs per tire, stock advans are 26 and my winter are 25 (thought they were heavy but for sure not, lol).

Maybe I will have to move it up a notch...been eyeballing this for next winter

**mlomker** · 04-06-2010

The Summer combination came out to 1lb lighter since the stock rims are 22lbs. The new lug nuts are also a lot lighter (enough to make you wonder how they keep the wheel on).

**mlomker** · 04-07-2010

Feeding the addiction. An acquaintance of Kracka's is parting a car that already has Rallye 4's. I wish I'd gotten that email a few days sooner! Some sweet parts on that ride.

So, these must be for the harnesses, correct? I think you said you will have real race harnesses?

The Rallye 4's use the stock seatbelt anchors rather than a harness bar. The nice thing is that they are easily detached when you don't need them since they have releases similar to an OEM seatbelt.
