My new rx7 has problems
 

I got my rx7 last week my dream car, it's a series 8 rb. when it test drove it at the dealer it had no problems, until I picked it up drove it when I went out. the car needed a wheel alignment cause it was pulling to the right.

when I turn my car, it makes these loud noises from the back, sounds like the tyres are rubbing are something. but it's the right size tyres, 235,45,17. I'm not a car expert but can it be the wheel bearings being screwed, or tie end rods or bushing, or some kind of suspension problem. The car is stock height

But at times the car feels bumpy at times on the road, and sometimes when I'm just driving straight the car goes left to right, I have to quickly move the steering back to straight otherwise ill go into someone else's lane, it did it the other day lucky, there was no car in the other lane otherwise, this car would of been a write off, and I'm not speeding driving normal speeds up to 60km, does the fd need a 4 wheel alignment, like a 300zx, I don't want to get a back wheel alignment finding out it was one of the above suspects.

If you hear clunking here and there especially like pulling into a driveway, parking lot etc then it can possibly be your bushings. I had those sounds in mine as soon as I got it. I have a 93 fd, and as far as the steering just randomly pulling on you my car does that too. Lol it generally happens if there's a bump or grooves in the road the tires follow right into it, I'm not 100 percent but it may be the type of tires. I've have diff cars with diff tires and no problem so I'm thinking it MAAAAY be the type of tires that it is. Possibly. I'm not an expert but it's just something I've also come across. I changed the some of the rear bushings and the clunks are almost gone. (I need to change the rest of them lol)

Have you check the front end of the car like ball joints and tie rods for play or a worn out wheel bearing. Does the steering wheel shake at speeds?

My car doesn't shake, idk about "slapsticks" car though? I've taken mine to 120mph and it seemed fine. I think it's my tires that pul my steering if I drive inside of a groove in the road.
